> A buy or sell offer system works pretty well for determining value. Georgists, which are the subject of this thread, explicitly say that taxes should not be NOT based on improvements, just the "land value". So if the improvements have significant value, buy sell doesn't work. I'll let you fight that with them. > Profitability (no matter whether your abstraction for ownership is property or political favour) as a fu…
Except Georgists determine your unimproved land value by looking at the improved land value of everyone around you. Otherwise, the proximity to Disney wouldn't mean squat in the post-upthread.
How, exactly, do you get from improved land value to unimproved land value?
It's arguably possible to approximate the value of a hotel+land across the street from Disneyland. How, exactly, do you determine what fraction is hotel (improvements) and what fraction is land?
Looking at other hotels in the area just tells you (an approximation of) the difference between the hotel values. That's not enough to determine the absolute value of any hotel.
