Can you elaborate on "or sell it"?

What would then stop corporations from buying insanely large bodies of water and holding it for sale so people are required to buy it.

usually but he said "Allow people to share water (or sell it)". There is no way they would allow people but not corporations.

Besides, the only difference between a person selling it and a corporation is just how they registered their business. A person can buy a bunch of water and hold it too.
