Eh, it’s a bit naive IMO. It’s nice to focus on your small, close-knit community, but it does not live in a vacuum. At some point the world (read: capital) will come knocking at it’s door, and if you’ve been sticking your head in the sand until now you will not be prepared for what happens.
Also, what if I don’t want my community to be small and close-knit? Lemmy is way more interesting now that it was a month ago, after growing by an order of magnitude. Ask anyone who’s grown up in a rural town and they’ll confirm this: tiny communities are fucking boring.
