And what's the problem with that?

This may be a hot take but I think there should not be forever private ancestral lands.

The city/state should periodically get the land back and resell it to cover the ever changing maintenance costs (heck you are paying this with the increasing property tax)

The city/state should have a relatively predictable timeline of when they can reliably gain control of a land back so they can plan development around it (particularly infrastructure) and not deal with someone who know they can just squat on such land to sell for an inflated price.

Having an "expiration date" on the land is a surefire way to stop ever increasing property prices, getting a home with a shorter remaining lease period might be preferable for some who is not going to stay there permanently but long enough to want to own a home and having these options be a cheaper option is a very good thing. Such expiration date also means it is easier to modernize each property as needed, this will not be the death of historic buildings because the city/state still can make exceptions for them if needed.

Also how many of the US-ians are getting a house as their inheritance anyways? Oftentimes when a generation passes away post retirement, their house gets sold to some investment firm and becomes a rental.
