Which circle most represents a community

Some countries try today to build communities as a new engine for sustainable growth. A member of a community means meeting others with mutual interests, and bilateral goals. We pivot and change yet shall not be forced to conform.
.
Where I come from, we live in communal lifestyles since we are born, yet this has devastated any sustainable efforts.
.
Where's the balance?
.
We have abused the way we live in community lifestyles, depriving others of their identity to the extent that privacy can no longer breathe. We have prejudged based on common sense as if we were living in an ideal circle, but it's not perfect and never will be.
.
For me, a community is like an organism, to grow as a body it should have different cells and various structures. Sustainable communities are those organic shapes never defined but ever dynamic.
.
Common goals can change, and inside a community can grow different other entities. We shall expect and accept others. Whenever we express our values, we might merge, we might split, and we might gravitate to completely separate poles.
