I have no problem with people having to pay to maintain ownership of their land. Land ownership is a useful farce. Every land owner is in possession of land that was "stolen", for lack of a more precise word. If we're going to protect people's right to claim land according to the "finders keepers" rule, we should ensure that the owner is making good use of that land. Property taxation helps to do that. (With many side effects, like exacerbating gentrification. That could be fixed, though.)
