Every neighborhood deserves a chance to survive without destroying others in the process.
If we assume that around 7,000 people could conceivably cooperate creatively, face-to-face, to manage their livelihoods then there would be about 1.1 million such settings. Thus the very rough "One Million Neighborhoods".
Many many jobs could be locals taking care of locals, keeping value circulating in the neighborhood rather than leaving to line unknown and often unknowable other's pockets.
