In most places, registered cars are taxed but unregistered cars are not, so classic/museum or inoperative cars can be owned without paying the government a fee every year. (This makes sense/feels fair to me. Registered cars are expected to be used and the use of cars costs the government significant money and has externalities on the public. Unregistered cars mostly do neither of those things at least no more than a bunch of shoes.)

I was expecting a museum as a rebbutal - well played!!!
