I've yet to see a single valid objection as to why LVT (Land Value Tax) should not be the primary tax, yet it's nowhere to be found in the political dialogue. Such a shame that the majority of the tax burden instead falls on the working class while the landowners get a free ride.
Land value (like all value) is subjective. There is no inherent value to land. What one person is willing to pay is not the same for everyone. Appointing someone to imagine a price for the purposes of taxation doesn't change this fact.
Whether it would be /accepted/ is another matter. But it's not impossible in the squaring-the-circle sense.
