I was simply answering the question in the post that I replied to: How are scarce resources allocated?
The answer is to let a rich, greedy bastard own it, believe it or not, and let them charge a DEAR price for it. This way, if a person wants to waste water, it'll cost them, and they'll soon run out of purchasing power, thereby protecting said scarce resource from irresponsible uses.
"Who REALLY owns the resource" is a moral question, has nothing to do with economizing and allocating the scarce resource in question.
