And as we're seeing here, if they can't get what they want one way they do it another way.
I've always thought the way out (besides just waiting until a neighborhood is an absolute shithole of a slum and can be redeveloped because poor people have little political power) is just to straight up bribe people. New developments have a "fee" that is directly applied in cash to other homes in the area to reduce property tax.
I think in most US states, the legal situation is actually that local governments are creations of the state. They are allowed to have their own ordinances and so on as a matter of convenience, to avoid state legislators having to bother worrying about every edge case that only comes up in one county, but they do not have a right to exist independent of the state saying that they do. There are exceptions, but municipal ordinances (and HOA rules) can be overridden by state law.
We don't /have/ to let all these little NIMBY fiefdoms exist. They exist at the pleasure of the state legislature, and therefore voters statewide, not just locally (modulo gerrymandering, a big caveat).
Municipal regulation has been keeping the neighborhood the same so why not expect it will continue to?
