Ultimately it is about protection of personal property. The value and and desirability of your personal property is directly tied to adjacent properties and the neighborhood. Height restrictions prevent someone building a tall building and blocking your view, which would have significant and direct cost to your asset value. Zoning restrictions ensure the neighborhood stays safe and quiet, another direct contributor of asset value.

This is not sustainable at scale, clearly density is necessary. But, there is a legitimate case for protecting private property values, creating density where it makes sense but not where it doesn't.

I wonder if there is any data on how upzoning affects suburban property values. I would prefer not to live in a single family detached house next to condos. Then again, the optionality to put 10+ units on a lot has to be worth something.
