Demand may be unlimited but humans will probably not be the most efficient suppliers of any goods in the future. Once it’s cheaper to run a robotic AGI than to support a human the economy will change dramatically. Personally I think the long term solution is just to ensure everyone owns enough capital to sustain themselves directly (permanent retirement, essentially), but transitioning to that kind of situation and then keeping it sustainable for thousands (billions) of years sounds fairly difficult.
