Hot, crowded, and running out of fuel: Earth of 20...
My limited understanding of desalinization is that we avoid it not because of the expense, but because it's environmentally damaging to put a giant pipe in the ocean sucking up water that happens to bring a lot of fish and such with it.

The biggest problem is what to do with the highly-concentrated brine after you've extracted the water - e.g.

Where do you think the water goes once we're done with it?

I think you severely overestimate how much water an average desalination plant can process.

No problem. Soon there will not be that many fish left in the ocean so that won't matter any more.
