Your idea of ownership is simplistic. Around me, the local government owns the home as can be easily found out if you don't pay your annual rent called "property tax".
Even if you are not a homeower, you still are not free and clear...
I would say that _your_ idea of ownership is simplistic. You seem to be implying that ownership is only possible if you can own something in perpetuity without any related responsibilities. It's the same idea as "taxation is theft" and other libertarian nonsense.
And if that was an actual statement people made, then you'd be right to say that. However, I think we can dispense with the strawman. Ownership exists in the real world, which means it necessarily conforms to the laws of the society in which it resides. Your view is a child's perspective on ownership.
