A very high LVT is a politically unserious proposition, because it would involve drastically raising taxes on the people who actually vote & hold political power in society- the middle class, upper middle class, and wealthy in suburbs and low-density urban areas. All of the alleged 'efficiency' gains you hear Georgists claim really mean 'middle class homeowners forced to sell their single family home to developers due to crushing tax increases'. Every day the evening news and social media would carry a new, tearful story of a family forced to sell their home. The white-hot rage of millions of taxpayers whose taxes drastically rise overnight would be enough to create bottled fusion- I suppose it would be good for the US in that you could finally find an issue that unites the most leftward Democrat and the most rightward Republican.
'Forcing everyone in the suburbs to sell their home to an apartment building developer due to ruinously high taxes' is the single most politically unrealistic idea ever proposed. LVT is certainly a clever way to make sure land is used efficiently, and probably a good idea in the abstract, and perhaps we could enact it when we colonize Mars. But implementing it on a country where many of the voters are living in 'inefficient' SFHs now is not ever going to happen
