There are communities the way they are now, in this modern world, these are not absolute as any individual among such would be in more than one community, and many having quite a few communities, and these communities consisting of other members with almost all of those having different communities each. But the natural arrangement of humanity was with communities which were absolute, an individual had a place in a community among others, and there was important value on doing things preserving the community, over one providing for oneself, and such individual would not belong to any other community. There individuals of a community lived in a common location where they saw each other, and indeed probably all knew each other, to greater or lesser extent. But with everything done for preserving the community there was stability in how they were living. These are the kind of communities we need now, and any such there would be would need sustainable living in how they live for the stability, providing for needs among them without lessening the wellbeing of the local environments and no dependence on any others.
