Not to say that water efficiency improvements in the agricultural space wouldn't be welcome, but rather that landscaping is arguably less important than even the relatively-unimportant foods, let alone the important ones.

So far, we've been responding to the crisis in a way that doesn't really allow people to make good trade-offs. For instance, I went to my parents house in a nice warm place, after a week in the fog, and my kids kind of wanted to play in the inflatable pool. My parents were bummed but asked us not to, because they're under mandates to cut back.

To feel better, we all went out for california raised beef burgers and gorged on walnuts. Several dozen inflatable pools of sheer deliciousness, all externalized.

Just kidding (sort of) about that last part, but this is the frustrating thing. Nobody is saying we can't use any water, we just can't use unlimited amounts of it. If someone goes vegan, avoids other water-heavy food sources, and doesn't wash his or her car, well, is it so bad that they might water a small patch of lawn or fill up the inflatable pool now and then?

This is what is so nice about markets, when people have to pay what something actually costs, they are unlikely to use as much of it.

Except, of course, you can now and then end up in a situation where someone rich buys "all" the water. One way to handle this is tiered rates, where it's cheap for the first bit, and perhaps very expensive after that.

Looks like the first 4 units (1 unit = 748 gallons per month) is $5.45, so once you get the tap flowing (sunk cost), I'd say that drinking water is "free". Even showers are pretty cheap.

The problem is that it doesn't go up by much. After those first 4, it's only $7.31. Still pretty cheap for something that we are supposedly in desperate need of.

I suppose we could just crank up that second tier - in theory, that would keep showers, drinking water, and so forth affordable, while properly pricing the use of water to produce burgers, walnuts, swimming pools, lush gardens, golf courses, and clean cars. Now that I think of it, rich people already consume more of that sort of thing anyway...

If it was regulated and you used your buddy connections to appropriate all the water usage rights then you still have your buddy connections once you have taken my water.
