It’s a made up number - no one normal uses this much water in a bath

They pretty clearly confused 0.25 cents with $0.25

Yep that's what happened.

In my defense, it's common "greengrocerese" to list a price that way. If limes are shown as "0.10¢ ea." on a handwritten card, you're not getting ten for a penny.

I still think taxing residential water is irrelevant, and that the difference between buying water at auction from the state and paying a tax for that water to the state, is that auction is better because price discovery tends to be.

The idea here is to set what appears to be a ridiculously low tax that applies to everyone. No carvouts so reduces arguments about fairness.

This highlight the large water uses (usually free in the millions of gallons).

If you aren't willing to say a gallon of water is worth a quarter of a penny - then we can usually stop talking about any supposed shortages. Retail / urban water use (ie, a bottle of water at the store, often 1/8th of a gallon - this tax is irrelevant obviously) already is wildly higher in cost than the "free" groundwater and river water folks are using.
