I want to build my own Matrioshka Brain out of Jupiter.
Post-scarcity is interesting from the point of view of the necessities of life being so close to free as to make no difference. But it's a long way to go before we truly will have more resources than we know what to do with. Our desires show a clear trend of scaling with our resources; we already have more wealth than any Mesopotamian farm peasant could ever dream of, and most of us could probably easily figure out what to do with another $100,000.
And if they evenly distributed them to everybody in some borderline mythical manner (because wealth isn't actually that portable), it would still roughly double or triple your personal wealth, tops. Again, I think most people could figure out what to do with that and would still after a year or two resume wanting something or other they can't afford.
