Please, taxing something doesn't mean the government owns it. Does the government own someone's home because they have to pay property taxes to the city for paving the streets and running the garbage service?

They are collecting rent as taxes and if you don't pay the rent they kick you out. I'd say they own it.

The homeowner just owns the liabilities.

Do you think the government owns you too, since they take a portion of the proceeds of your work and will put you in jail if you don't pay it?

Nope

Good point. At the end of the day, men with guns will come and put you in a cage if you disobey. Drafts are pretty nightmarish too, if you think about it.
