A land value tax would make it easier to convince people to do zoning differently.

It's also a feature that it would have a larger impact in areas where land value is high and less impact in areas where land value isn't high (so "most of the US" doesn't really matter).

It would also ensure users of land like wide roads (with on street parking), parking lots, etc, pay their way

The money goes to the local administration, who then can spend it on truly public places like parks, offering tax breaks to businesses they want to attract, subsidising housing, etc, which everyone benefits from.
