I assume that the engineering would be run like an open source project. Debian is a good example, or the Linux kernel. The best stuff is decided by the contributors and anyone is welcome to fork and compete. Actual labor of manufacturing and distribution is handled by competing companies (which may be democratically operated) but the tech is open source so “lock in” (which is a man made inefficiency in the market) can’t do easily occur.

Life always takes work to run. Getting to work every day to pay for food at the store and run errands etc just to do it all again tomorrow feels like beaurocoracy too. I’d much rather have a world where the work I do to support myself is to vote on local community matters (the next merge request, etc), instead of commuting through a zoo and looking out the window at the sunshine.
