Why a Public-Control Taskforce Cannot Calculate Fair Water

On 2 September 2026 the Cabinet Office announced three new cross-government taskforces in the Office for the Prime Minister and Cabinet. One of them is a public-control taskforce. Its brief is housing, water, energy and transport. The charge is that those essentials have, for decades, “suffered from over-privatisation, leading to high costs for the public.”

First Secretary of State Louise Haigh will coordinate the work with departments and regional mayors. Immediate action, the release says, will focus on “everyday rip-offs,” declining town centres, and “the failure of many privatised utilities to deliver basic services at a fair price.” The taskforce will examine how public control “can be utilised to return them to public service, and bring down costs for families.”

A day earlier, on 1 September 2026, Prime Minister Andy Burnham told the House of Commons that Britain’s water industry “stands as a leaking monument” to a country “run in the private rather than public interest.” Later in the year, he said, a ten-year plan will set out “stronger public control over these essentials.” The press release is the machinery. The statement is the diagnosis. Neither is a price.

What the Story Claims

The mainstream reading is straightforward. Privatised utilities charged too much and delivered too little. Public control will make the same services affordable and accountable. Haigh put it as putting people “back in control of the things that matter most to them.”

Burnham’s Commons statement supplies the bill of particulars. Too many areas, he said, saw water supplies disrupted this summer for lack of reservoir capacity. Tourism was damaged by sewage spills. Household energy bills, he told the House he had heard on a farm near Truro, are the highest in Europe. Grid connections take too long. The implied claim is that a Whitehall taskforce, working with mayors, can compute the missing fair price and then post it under public control.

The release is careful on method. It mentions “market reform that could support these aims.” It does not publish a tariff. It does not say who will bid for the next cubic metre. The fair price is the output the committee is assumed to calculate once ownership is rearranged.

The Austrian Diagnosis: A Fair Price Without Exchange

Ludwig von Mises (1881–1973), the Austrian economist who spent his career showing why socialist planning cannot allocate scarce goods, argued in his 1920 essay “Economic Calculation in the Socialist Commonwealth” that without genuine market prices no one can tell whether resources are being used for more or less valuable ends. That is the calculation problem: a number can be computed without being a price. A price is the bid and the offer that clear a particular exchange. A fair price posted by a taskforce is an administered residual. It is what the office thinks households ought to pay after the ownership of the pipes has been rewritten.

Water makes the cut concrete. A litre in a Cumbrian reservoir, a litre treated for a kitchen tap in Liverpool, and a litre discharged as treated effluent are not the same good. Each has a different opportunity cost. A market discovers those differences as bids. A taskforce that returns the four sectors to public service still has to decide how much to spend on reservoirs, leakage, sewage, and household bills. Changing the letterhead on the undertaker does not generate the missing exchange. It only changes who writes the residual.

The same arithmetic applies to housing, energy and transport. They are not one price. They are millions of local trade-offs: a spare room against a commute, a kilowatt at 5.47pm against one at 2am, a bus that runs empty against one that does not. Public control can forbid a private tariff. It cannot tell a mayor in Cornwall whether the next pound should go to a reservoir, a grid connection, or a night bus. Mises’s point was never that utilities are unimportant. It was that calculation which does not rest on exchange cannot rank those uses.

The ten-year plan promised for later in the year will, if the statement holds, set out “stronger public control.” Watch the document for a formula. Ofgem already publishes one every quarter for household energy. A formula is still an estimate without an underlying exchange to estimate from. The taskforce can coordinate departments. Coordination is not calculation in Mises’s sense.

The Historical Parallel: Two Statutes, One Missing Price

Britain has already reorganised water twice by statute. The Water Act 1973 created regional water authorities and transferred to them the functions of the old river authorities. The Water Act 1989 then transferred the water authorities’ functions, appointed water and sewerage undertakers, and created the Director General of Water Services. One Act bundled supply into public bodies. The next Act unbundled those bodies into successor companies and a regulator. Both were honest as law. Neither discovered a market-clearing price for the next litre.

That is the structural rhyme with this week’s taskforce. The 1973 authorities posted charges under public ownership. The 1989 undertakers posted charges under licence. The 2026 taskforce proposes to examine public control again so that services can be delivered “at a fair price.” Three institutional costumes. The same missing bid. A director-general of water services is an office that stands in for a price the exchange did not set. A cross-government taskforce in the Office for the Prime Minister and Cabinet is the same office with a wider brief.

Burnham told the Commons that from the 1980s the country “took a series of wrong turns,” with economic power privatised. The Austrian reply is narrower than a brief against the 1980s. Privatised undertakers can fail to maintain reservoirs. Public authorities can fail to maintain them too. What neither statute produced, and what a taskforce cannot produce, is a continuously tested price for each use of the water.

Why This Matters for Sound Money

Chapter 8 of Rails to Freedom, in Part 3, treats DeFi protocols as the first financial institutions that emerge on open infrastructure rather than on a licence. Aave sits in that chapter as permissionless lending without a bank. The protocol does not convene a fair-rate taskforce. Suppliers earn interest funded by borrowers. Borrowers post collateral that must exceed the debt. Rates move with utilisation. If the claim is wrong, a health factor falls and a liquidation closes the position.

Chapter 9, “Governments in Retreat,” is the matching implication. States can reorganise who posts a tariff. They cannot prevent users from exiting to rails where the residual is not posted at all. A public-control taskforce is the older tool: rewrite the owner, then announce that the new owner will be fair. Sound money and programmable settlement are the newer tool. They do not require the Cabinet Office to calculate the right bill before the next litre can be priced.

What Markets Are Already Doing

Aave is a decentralised, non-custodial liquidity protocol. Its documentation describes Aave v3 as running on Ethereum, the public permissionless chain launched in July 2015, and on other major networks. Users supply crypto assets to earn yield. They borrow against collateral that exceeds the borrowed amount. Positions are always over-collateralised. Risk is tracked with a health factor. When that factor falls below one, external liquidators can repay part of the debt and take collateral. Interest rates adjust with utilisation. Supplier yields are funded by borrower interest, net of a reserve factor.

That is the earned contrast. The Cabinet Office can launch a taskforce to examine how public control “can be utilised” so that water arrives at a fair price. Aave does not examine fairness. It posts a rate that moves when more of a pool is borrowed, and it closes positions when collateral is no longer enough. No First Secretary has to coordinate the next liquidation.

This is not a claim that Aave prices English water. It is the narrower point the 2 September release invites. A residual called “fair” can be written into a press release and a later ten-year plan. A borrow on Ethereum can be undercollateralised for a block, and then it is not, because the protocol sold the collateral. One operation is a taskforce. The other is a price.

Looking Ahead

Watch the ten-year plan for whether “stronger public control” arrives as a new owner, a new formula, or a new bid. Watch whether the taskforce publishes a tariff for water, or only a method for coordinating departments and mayors. A method can be tidy. Tidy is not calculation.

Aave will not wait for the Cabinet Office to finish examining the four sectors. Pools will keep being supplied and borrowed on Ethereum. The next liquidation will keep being a function of collateral and a health factor, not of a residual posted after over-privatisation. Only one of those operations discovers whether the next unit was worth taking.
