It's not even the "super" rich. They don't care what you do. They can afford walls, hedgerows, extra land as a buffer, the finest sound deadening windows, etc, etc, etc. And they can afford to live among people like them so pretty much all that is only of limited relevance to begin with. They make the rules of the game so they make money and their assets go up either way.

It's some jerk who makes $200k who can afford the house but can't afford to not care what their neighbors do that drives all this at scale.

He's the one trying to scheme up some way to get the government to use other people's tax dollars to threaten them if they try and do something he doesn't like, because that's his only lever to pull. And there's enough of these jerks the government(s) pander to them. The result is everything gets stifled and red-taped. Can't run a bar here. Can't have an apartment building there. Can't have too little parking, but if you have too many cars you're running a junkyard, and on and on and on and on. It's these people in aggregate that result in the existing body of regulation of which there always seem to be a few lines that can block any given development.

And then they have the gall to turn around and whine about the sum total of all this. Not enough housing, not enough amenities, what does get built is ungodly expensive.

"man, this park sure is dirty" <throws cigarette butt on ground> "I wonder how it got that way".
