... and pricing out existing residents in low density housing by taxing them to oblivion.
I never understood this argument. People are not priced out of their homes. Their homes are rising in prices so they actually have assets to match the price increase. Yes they might not be able to afford the tax, but they have a million dollar asset that they could use. The whole point of the tax is to disencent a single person living in a huge house all by themselves.
You're literally proposing a scheme that views removing people from their homes as beneficial. Your values don't match with others. That's the disconnect.
And by the way, that increase in value over the years is because other people want to live in that area. Perhaps we should disincentivize that instead of punishing the people who made it a nice area to live in.
