Part of the issue is not systematically using a pricing structure that charges disproportionately more for usage above high thresholds.

The 101-level "solution" is to just raise the price to account for demand. The problem with that is that it treats all usage the same, whether it's a residence's first gallon or an alfalfa field's last gallon. But the former is something we need to protect.

It makes sense to price water, and electricity, in a fashion where the first X costs a certain amount, and the next X has a higher rate, and above some percentile of usage it has a much higher rate, and at some percentile of usage, customers should be very nearly paying for new required utility infrastructure themselves. That allows using pricing to solve supply problems, without penalizing normal levels of usage.

Some utilities already do this. But if there are actual issues with having enough supply for both datacenters/farms/smelters/etc and residential usage, then they're not doing this well enough, or don't have the pricing correct.

This causes major market distortions and worse outcomes than the econ 101 solution.

The problem is that water isn't traded on a normal market at all. Lots of people have historical water rights and pay nearly nothing for their water use. There's byzantine regulation and many have the right to use for some purpose on their land but not to resell, so the market cannot allocate to more efficient use.

If you just let the 101 level solution actually work, water prices will rise until inefficient uses like water-intensive agriculture (not even all crops!) are pushed out. Urban users easily outbid almost all agricultural use, even at what any person would consider dirt cheap prices. For example, desalinated water, which is considered expensive for agriculture, can be 40 cents per cubic meter of water. That's a lot of water! Usually the last mile of urban water delivery costs more than that.

The amount required to satisfy all urban use, including water hungry lawns etc, and datacenters, corresponds to a very minor reduction in agriculture. Perhaps even just changing which crop is grown or switching irrigation techniques.

Charging more to higher users, price discrimination, causes several problems. First, it creates an incentive to cheat. I'm not using all this water myself, its for this whole group of people who "live" here. Don't allow this kind of spreading (somehow...)? Now you actually screw any business or institution that serves a lot of people. A farm produces food for thousands- do they count as one user? A park uses much more water than a garden but serves many more people. Whatever framework you create will require another bureaucracy to run. Lobbyists will find or insert loopholes for their friends.

The heavy users actually improve the system robustness, in both electricity and water. Their higher demand pays for more supply infrastructure, which itself often benefits from economies of scale, and in a shortage they may even be more responsive to price increases due to their high use.

I disagree. A large part of the cost of a utility is fixed per customer. Or any product really. That's how bulk purchasing makes sense. I can get 4x the product at a bulk store for 2x the price. Instead of being prejudicial about the use case, let's just charge what the utility actually costs. Include capital, operation, and decommissioning costs. That way, if you get a sudden spike in demand, you have the cash flow to issue a bond a scale up.

  • This would be an extremely regressive pricing structure that still has the same punchline: somehow residential users pay more to still not have any water.

We don't do this for gasoline (in most countries), even though it is also vital for life. And yet people can still drive, afford to eat food grown with fertilizers, use plastic, and so on.

Turns out markets are pretty good when you leave them alone. But when they're not left alone (as is the case with water today!!) you get some weird shit.

  • > We don't do this for gasoline

    No, but commercial trucks use diesel, which carries about 25% higher taxes per gallon. And vehicle registration on semi-trailer trucks is significantly higher as well. They pay, on average, between $25,000 and $30,000 in taxes and fees each year.

    > Turns out markets are pretty good when you leave them alone.

    No, they aren't. They're ridiculously bad when you leave them alone because someone captures the market, ramps up anti-competitive practices, and immediately begins rent-seeking as hard as possible.

    Free markets are pretty good at finding good prices. Markets that are left alone do not remain free. That lauded "self-interest" encourages businesses that have reached nearly 100% market share to increase profit in other ways.

    • Heavier commercial trucks that run on diesel tend to cause more damage. Scales with roughly 4th power of axle load.

  • Gasoline is absolutely rationed when it becomes scarce after having been plentiful.

    When hurricanes come to South Florida, the well off migrate North to wait out the storm while the poor suffer the dangerous conditions. Part of this is due to the price spikes of gasoline in the local market as supplies dwindle due to fewer truck shipments and refineries shutting down for the storm.

    Water is similar. Both water rights and water utilities are gamed by people who have resources. The people that are hurt are usually poor utilities bill payers, rural residents who are the first to lose service when wells dry up, and anyone who thinks they have water rights until an upstream user exhausts their expected supply.

    The “markets work” heuristic is frequently wrong if you don’t glaze over the very many counterexamples.

    • Yeah but that response is stupid, irrational, makes shortages more likely and discourages people from taking action when they need to do something different right now. In an emergency situation, people who can provide more of something that is in desperately short supply should be paid more. People consistently adopt a strategy of trying to not pay them more and it's one of those really annoying cases where people's instincts are primed to make them band together and do something predictably foolish.

      Rationing is an inevitable response. But to say that is like saying witch hunts are inevitable - they are. They're still bad ideas. People who can maintain access to their higher reasoning should resist them.

  • Gasoline is heavily regulated and subsidized. Leaving the oil market alone resulted in Standard Oil, and we obviously don't want that again.

    • Standard oil not only reduced consumer prices for gasoline, but was already losing its monopoly to competitors during the antitrust trial.

  • excuse me? leave the markets alone? to do what? continue screwing people over with the cost of living? at some point the government needs to step in when greed outstrips the ability of the consumer to meet the demand. capitalism on it’s own will demand ever increasing profits and that is simply unsustainable for any civilisation
