All those things you described are proxies to control resources and produce security. The money, the attention, the influence etc. Yes, structurally those things become less important if there are fewer people.

But it doesn't matter! People are unpredictable and difficult. You don't meet most of them anyway!

You don't need to think about money in the same way anymore if you can produce the goods and services you need directly, using land, productive capital and robots that are approximately as capable as humans.
