Ocean is full of water. It just costs money (maybe a lot) to desalinate it.

(And to move it).

That just pushes it to another zero sum game of money.

Why does it matter if it's zero sum? Sometimes things we need aren't free.

The GGP post was claiming housing was zero-sum. Posts responding to it seem to be trying to contradict it.

My point is that in a world of finite resources, it's going to be zero-sum at some point whether that's land, water, money, labor, or something else. It's not good or bad, but you do have to pick your poison to a certain extent.
