No, but pooling and sharing every resource is.

Human cooperation needs to be VOLUNTARY and between a small circle of people you know and trust.

In the 1990s, an anthropologist named Robin Dunbar estimated that in general, we can only maintain between 100 and 250 meaningful relationships. I'm not exactly sure I agree with the number entirely, but there is precedent throughout history.

One is much less likely to screw over a person in such a small and connected group than they are to screw over millions of people living in the city they live in, which is why pooling resources will never work on such scales, and perhaps why sudonaka had this reaction
