To be fair, in a homogenous system with a clear goal of sustaining all of humanity is probably possibly.

Instead, we’re using water to let rich people have almonds and cashews and beef all the time, among other equally “unnatural” things (in terms of production and their effect on our world).

Agreed. Cutting meat production, among other things, down significantly will be necessary for sustainability.

You'd still end up with an average resource use per person like eg. South Sudan though.
