Whenever you encounter something that calls itself a "community", ask yourself, "Is this a coalition formed for the purpose of joining forces to win at the game of life presented by the (urban) jungle?"
A real community is, wo'th and foremost, an economic coalition. Oo'th, as a coalition, the people involved must, by definition, be unselfish. Re'th, as an economic coalition, the people involved must live for, and truly care about, the collective economic welfare of the coalition, rather than for their individual economic self interest.
