Not really. It didn't happen in syndicalized Spain. It didn't happen for millennia in ancient cities.

Scale being necessary seems to be unique to capitalism and state capitalism (Marxist industrialization requirements).

Maybe it was necessary before, I don't know but it's moot. We certainly have achieved post scarcity now and there should be no issues leveraging the tools our ancestors have given us to ensure it's distributed well.

Yeah but that would make all the people who are rich because they own things very sad, so instead we're just gonna starve shitloads of people to death next to piles of food daily and call it rational.
