That's like saying that you never own your car because you have to put fuel in it for it to run, or need to have it registered / tested, or you need a licence to be able to operate it.
If you redefine "own" to mean whatever suits you, yes, you're right.
You "own" the property because people agreed on that people can "own" land. Same people agreed on tax ownership. Like they agreed on other kind of taxes.
Renters end up paying the property tax as well. Sure, the landlord handles the money at some point, but there’s a solid argument that the tax is ultimately paid by the user rather than the owner.
That's true of all taxes. It doesn't mean there shouldn't be any taxes. We should also be able to agree that taxing wealth is preferable to taxing income, at least morally, because hard work should pay a little bit more, and simply owning things should pay a little bit less.
I'm simply arguing that work is taxed too much in comparison to wealth. I am not saying taxes should go up even more in general, necessarily.
I'm sorry to be this blunt, but this is a stupid argument. You already "renting" your plot of land from the government. Without government, your home has no protection at all and you own nothing.
I have no idea where you live. As a European, I think that what you just said, is batshit insane.
I trust, and I have to trust, that my government acts (mostly) in my interest. If I stop doing that, I'm at war with my own government and I leave the "moral territory" of democracy. Nothing good can come out of that.
You have chosen to put yourself in a position where either you think the government acts in your interest or you have to be at war with your government. The answer lies somewhere in between.
If you redefine "own" to mean whatever suits you, yes, you're right.
