"relies on being able to determine the unimproved value of the land.
This is impossible."
1) my property tax includes 2 line items, land and improvements. So clearly not impossible.
2) it's also irrelevant. (Land value) tax just has to be plausible and reasonably consistent. Property taxes are contested all the time and are based upon interpolations and extrapolations of recent sales when possible. All that is required is that the taxing authority comes up with something that the owner pays.
