You can easily write a law that looks like this: There is now a water usage tax. It applies only to water used for data-centers. It does not apply to residential use, agricultural use, or any other industrial use.

We do preferential pricing and taxing all the time. My home's power rate through the state owned utility is very different than if I consumed the exact same amount of power, but was an industrial site. I just checked and my water rate at home is also different than if I were running a datacenter. So in all actuality we already discriminate for power and water based on end use. at least where I live. Most places I have lived have different commercial and residential rates.

In other words, the price of beef can stay the same.
