My main concern is the idea that we would use property taxes as a tool for taking people's property.
If I buy a wrench, it is mine, outright, forever. Owning a home isn't like that. You only get to keep the home for as long as you can afford to pay the property taxes. there are different meanings of the phrase "property ownership". I think the misunderstanding here is that you are applying the expectations of the wrench kind of property ownership to the housing kind of property ownership.Maybe a thought experiment is useful. Imagine owning a car, where at any point in time, the market can decide to magically upgrade your car to a high-end luxury sports car. On the one hand, your car is now much more valuable, but on the other hand, gas and insurance rates just exploded, and you may no longer be able to afford the car anymore. Home ownership is less like owning a wrench, and more like owning a magical transforming car.
