> For example the rant about "capital gains taxes" doesn't include the reason why you can't tax something that is not sold yet. It is wrong on so many levels. Suppose you have a home that is going up 10% and is worth +50000 USD. You haven't sold it yet, but you owe a tax out of the blue. Isn't that a bad idea?

I take your larger point, but for property specifically, we already do have a system in place for taxing unsold assets.
