> If someone owns a collection of old paintings, why should they be taxed based on their value?
replyIf someone owns a collection of paintings which they're not trying to leverage as an asset, there's no reason for their market value to be known. But if they're putting the paintings up as collateral for loans or something else that demands our participation, then they can pay the rest of us for that privilege by paying taxes on the value of the paintings. Otherwise what reason do we have to acknowledge their property rights?
Perhaps at one time you could've said: "they'll, in turn, acknowledge yours." But so many of us have no property, so that deal is deteriorating.

replyThis is a good idea since it doesn't distort economic decisions, but has not been implemented in many places.
