Also, water is not readibly fungible as it’s not generally economic to ship large distances. So either you have it, or you dont.

If you do have it, often you have more than you can store or use effectively (the rest just runs off).

If you have a lot of water, then going to a bunch of effort saving it is indeed silly.

If you don’t have a lot of water, then it is indeed essential.
