Communism

I presume much the same ways as they did inside the city…with work.

Grab a quiet field(there was more available space before there were so many people), put up some temporary shelters, hunt and forage, cook a camp potluck. Sure, go without the certainty of stone and plumbing for awhile, but it could be done when you had the skills and the will.

Unlike the the other guys who had to realize they weren’t very good at or comfortable with the whole…working thing.
