Your additions still fit my premise; that we should all be contributing to the “spaceship”.

As it relates to one of the other comments - the homeless people outside his apartment do not, in any way, contribute to the spaceship. They must be provided for constantly. That’s why people take issue with vagrancy, there’s no contribution back after they have taken.

So in the past some people took solutions to this problem to the extreme because they'd decided a certain set were "surplus to requirements". Obviously you're not advocating for that. Given that we are historically piss poor at correctly deciding who "is not contributing" and, actually, the "ship" still appears to be running (and if it isn't I strongly doubt it's because of the vagrancy of a few) is it really an issue whether a few don't actually do work/contribute?
