Oh, c'mon, the word "community" is thrown around willy nilly nowadays. Every day I read something about the "tadpole-owning community" or whatnot.
It could be the other way around: we are born into families and nations and therefore we post-hoc accept and value them.
We can't wait to leave and get away to the big city and then, eventually, from time to time, we yearn to return home. Not due to some innate preference or unexplained genetic mechanism but simply because that's how we grew up.
However, few are willing to give up their new-found freedoms for a circumscribed tribal existence. Which doesn't mean we can't or shouldn't honour our pasts.
