I get that there's a certain type of person who'd like this, but for the majority of people, you're highlighting the reason people don't like HOAs. You're creating a little city, whereas most people just want a home.

In any case, as I may have said somewhere - if you exclude condos, only a small percentage of HOAs have any shared facilities. No courts, no clubhouse, no pool, etc. When I was house hunting, easily under 10% of HOAs had any shared area.
