Most people don't think you should be able to buy up a precious thing and squander it. Locke--the guy who came up with life, liberty, and property, based the property right on the owner's ability and duty to improve. Leaving apartments vacant doesn't sound like improvement.
Taxes also aren't coercive; even SCOTUS hasn't held that. They've held that benefits can be, but not taxes. That's a right-wing anti-tax talking point that has no other principle. What amount wouldn't be coercive? Under what conditions would it be not coercive? What taxes are and aren't coercive: gas taxes, capital gains taxes, sales taxes? The idea is to just say "taxes are coercive" and close the book, which Grover Norquist might buy, but we've got a civilization to run so we need to do better.
