>My main issue with a marginal property tax is that the areas with high property values already have enough taxes generally for the things property tax covers.

The big issue in my opinion is defining property/wealth (not just land and cars, but also intellectual property, art, etc), and then the feasibility of appraising all of that, and then litigating those appraisals (for the populace as a whole).

Seems like it could get into quite a bit of the country’s resources going to refereeing the game, which at some point takes away from productivity.
