I can't think of how a private, but still public-access, park survives without a rich benefactor eating the losses, even today.
edit: oh i just realized a huge one in my daily life: the intervale in burlington is owned by the intervale center but the community garden is managed by the city's parks & rec. also there are a ton of public trails on that private property.
If LVT is implemented, land owners will have a financial incentive to sell off the plots, and the spaces will be gone.
If someone else can develop the land, why doesn't the current land owner
As far as I am aware, they are able to survive on their membership or visitor fees. But major improvements do take larger donation.
A LVT could thus accidentally wind up like a window tax in that it could wind up discouraging efficient improvements to human conditions out of a misguided attempt at improving perceived fairness.
Any LVT would just involve scaling up land portion and setting building portion to zero in our current regimen. It wouldn't require anything novel. The 501c3 exemption is not something new I'm suggesting.
The value of the park is going up, is that not recompense?
