What might those be? Can you expand on why you don't "like" it...
2. Why land, specifically? Why land only? It's not the 1800s anymore, and land is not either the primary asset or the primary source of wealth. Why single it out as the thing to tax? It feels like a theory stuck in the past. It needs to explain why, in 2023, land is the one thing that should be taxed. I've seen handwaving, but nothing that feels all that solid. (The one argument that has at least some merit is that no more land can be created, unlike everything else. True, but so what? There's a maximum number of bitcoin, but Georgism doesn't say to tax them. Why is land the one magic thing to get taxed?)
3. It is easy for the rich to have a smaller proportion of their assets in land than it is for the middle class. (Unless they rent - and then they wind up getting charged for the tax without having the benefits of owning the land.) LVT - if it's the only tax - means that the rich can easily wind up paying little or no tax. I'm not of the "confiscate all the rich's assets" crowd, but letting them pay almost nothing doesn't sit right with me, either.
Also: There's this one annoying trick where "they" (the rich) constantly get whatever they want whenever the thought pops up and thats normal but any small step taken to roll back the trend and that is often popular or at least a cult-fave is radical and insane.
Edit: Family Guy already did this and they did it the best (frivolous difference in belief or opinion -> This man is insane -> custody -> comedy)
