I agree, in so far as that we have truly a lot of problems to solve, new borders to breach out towards, and a mutual aid system like an unconditional basic income could be the foundation for people in their societies big as big and small, to start solving those problems, challenging new frontiers, out of their own intrinsic motivation, or motivated through their social surroundings, societies.

Universality isn’t a questionable concept to me here, because how else would you get people, societies, to start looking at solving their problems, when instead you give em conditions, hurdles, riddles, trifling matters that offer a lifetime of make-work to solve.
As if third parties with no insight into people’s problems could ever know what’s the course to take to solve a problem.
