Serious question. Is it possible to do this with very large populations? It seems like it might get inherently more complicated with several tiers of government (federal, state, county, city, etc...)
It definitely feels like Dunbar's Number is a gate to keep this from being effective in large communities.
If we can't view more than a finite amount of other humans as being "real," how do we begin to get massively large groups of humans to care for one another? This is a question I don't have the answer to.
