There’s an interesting dichotomy between the “in a capitalist system, you can do whatever you want“ and a “The capitalist system will optimize everything for maximum efficiency“ lines. It’s one of the things that I think of whenever I see sharing economy stuff, I’ve seen the occasional quip mentioning old complaints about how in a communist system you wouldn’t have a car, you’d have to share one, which is totally unlike our current system with uber. 

That baugruppe discussion reminded me of it, it’s an attempt by libertarian-leaning people to build a commune to solve problems they have with the housing market.  Feels like it really should be built at sea though.
