I'm very much for private ownership of property, not sure why you would think otherwise. All I've said is to do what just about every other state does: if your property is worth $200k, you pay $2k that year in property taxes. If it's worth $2 million, you pay $20k. This isn't hard, and it isn't controversial.

Edit: just to appeal to authority: every single legitimate economist agrees with me on this as well.
