> I can think of a few neighbor situations where an HOA with teeth would have been welcome. The most specific involved someone getting a big angry dog breed, neglecting it, and then leaving their gate unlocked so it got out. That one was eventually dealt with by the city, though.

Wow, no. That should only be dealt with by the city. I cannot imagine the types of misuse and abuse that would come from the self-centered, small-minded petty tyrants that want to be on a HOA board deciding what breeds of dog they'd like in their community. It'd be a bunch of "toy" dogs that frankly I find far more obnoxious than larger breeds with incessant yapping. I don't get to make the decision that that's a problem, because it's a preference/annoyance, not a problem. But you can guarantee that that's the kind of thing that happens.

> I think the nightmare situation is a busybody HOA that starts going after things that don’t matter, which would be hell.

I think many HOAs are exactly that, because often the kind of person drawn to being on a HOA board is exactly that. Just like they're often the kind of person to post on Nextdoor, "Hey, there are a bunch of black teenagers I've not seen before walking down the street."
