The technological approach is more interesting to me. If you can make distributed manufacturing efficient enough that a single person or group of people can own the capital needed to sustain themselves, you place a lower limit on the extent to which market-based social contract regression can harm a population. Alternatively, from the capitalist angle: companies that directly trade goods for labor are in a unique position to profit from a glut of labor that is not competitive on the global market.
This isn't a new idea. We call them communes. They have a well deserved reputation for being a shitshow. Probably because what they're trying to do -- boil a globe-spanning sprawl of infrastructure and trade down to an acceptable MVP -- is really, really hard. Unlike the world economy, though, that difficulty is a function of technology, rather than politics. Technology improves over time. Politics does not. Which means there's probably going to be a crossing point. I haven't the faintest clue when. I do my (tiny) part by contributing to "industrial" open source projects (mechanical and electrical modeling and simulation), which sorely need any attention they can get, regardless the underlying philosophy.
