> The value of water to a person dying from dehydration is infinite compared to someone who's adequately hydrated.

But most people are adequately hydrated in steady state, and to them the value of water is not that high. Since today it is necessary to sell an item for the same price to everyone, selling water for infinite money would lose nearly all customers.

(Not to mention that it’s possible to acquire water from natural sources, for free)
