The author casually mentions this but basically the main reason through history to build communities is the existence of kids, which he literally decided not to have.

I'm the opposite, I don't like or want a social life, I live comfortably, but by having kids I have no other choice than to participate in a bunch of communities just as a byproduct of trying to be a good dad.

Even the communities anyone participates today were likely built around kids in a past time.

The rest of the article is just trying to overcompensate for the decision of not having children.
