"Consumption" doesn't mean disposable, it means homes should be used to be used to fulfill needs and desires, and not used to increase wealth (as an investment good).
Easiest way to do that is a land value tax; the home itself is not what is appreciating in value anyways, the land is what is appreciating.
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?
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.
