Can we just stop with this post scarcity nonsense.
We are not in some post scarcity utopia. We are rapidly running out of real-estate. Yes we can build up but many was not meant to live in endless concrete jungle, most people don't really want to, but the consequence of unbound population growth (which does seem to be slowing, for reasons of scarcity) would be ecological collapse as we take to much away from the remaining natural spaces.
The cost of energy is also going up. Wind and Solar don't actually lower costs, if they did they the oil majors would be building them at the same time they develop fields. you can't make money on window and solar without major tax subsides and fake "green" programs, where because you are in a "green industry" you get side step the impact studies and mitigation requirements any other commercial activity would be required to support/execute/subjected to, whales and birds be damned. - Energy will either continue to increase in cost until someone can make money in wind or we will develop new Fossil resources, but those will also be more costly as the recovery complexity only goes up as we deplete them.
The costs of food continues to rise, yes yes distribution not production problem, blah blah blah.. Might be/likely is true about being able to feed everyone for quite sometime by reducing waste vs output growth, but right now there is no *viable* plan to reduce waste on that scale, and the costs of production are rising, inputs like chemical fertilizer are not getting cheaper and they wont.
As bizarre as it seems we are circling back around the scarcity being about basic needs like food and shelter, because advanced manufacturing has made what ancient man saw as luxury very abundant. In most of the USA $15 will put a very powerful computer and communications platform in the palm of your hand, but it will barely feed you a week at the grocery store - (think homemade pancakes from scratch for two meals, and canned veg/beans for dinners). We have luxury poverty, where people can get some very nice things, but yet can't afford the most basic things they need. Why because there is real scarcity under those basic things.
The answer to most of this, is actually reset the international systems. Every nation/region needs to find away to sustainability produce enough food for their own population. Nations that are net importers of food or have net emigration should be subjected to heavy trade, travel, and monetary, sanctions by other nations. That will force them to fix their economic balance and focus on the right kinds of production. It will also re-balance more developed nations. There are lot of people that just are not fit to work in high-tech, and there are not enough jobs in 'trades' and ditch digging to provide a long term outlet. We actually need economics that allow workers to earn a living wage for 'low-complexity' activities like seamstress, and basic furniture jointing etc; put another way we need enough protectionism to that the domestic appetite for basic household items is satisfied primarily from domestic sources. - Capitalism at the domestic scale will work well for organizing that, after all it did in the past. Capitalism applied at the globalscale, with nationalistic actors looking to game the system will continue to fail.
