If you're trying to water a cornfield big enough to feed your family, a fraction of a cent per liter might still be too much, though (and again we would predict that rationing measures would favor politically powerful agribusinesses and perhaps the Indian reservations over most small farmers). But it's not about dying of thirst.
A fifth of an acre of higher-water corn will provide more than 10k calories per day for a year. So about 5 acre inches, about half a million liters, if the price spikes up to 0.1 cents per liter that's $500 of water.
I'm not particularly concerned with the viability of people farming their own food but that seems plenty cheap.
Even desalinated water would be under a thousand dollars, and we could 10x the water supply at that point.

If the system allocates free water which can then be easily resold, the end result is basically the same as everyone paying but some entities get free money. Anyone expecting to buy their water should be no worse off.
