The relationship is that private property only exists because of a system that enforces it and provides many of the services that lend it value. Whatever you think of this system, the two are deeply intertwined.

And, crucially, the relevant services all have easements that supercede your desires to do whatever you want on your property. You don't have the right to NOT have a powerline going down the street on your property, or a city sewer line, or a sidewalk, etc.

So the next logical step would be that property tax to be extended over all your property, not just real estate. We already pay property tax on cars in Europe, but not yet on bank accounts, clothes on our back, collection of family photos, etc. Probably with you guys, it's already on the way.

Cars are registered property, just like houses. Clothes and family photos are not. How would you tax them without registering titles for them?

I don't want to tax any property, if that is not already obvious. It is already paid and taxed once.

I agree that the distinction between property and other forms of wealth doesn't make a lot of sense from the perspective of taxation and mostly exists for historical reasons. Especially because the wealthier the individual, the smaller the percentage of their wealth that is derived from property. Small amounts of wealth like clothes and family photos probably shouldn't be taxable in the same way that small amounts of income aren't.
