Ridiculous comments. Now you have a partial copyright on the USD?
Or you have ownership of a dollar to trade. The problem with that is the USD can be in an accounting column the art makes no difference. But take the art with the nominal amount off the bills and you have nothing.
Then you have no point. Your comments to date were about valuations. If party A claims to sell something and you say it is not a contract or property rights then you are talking values or even fraud if party B buys the item. Now you say you are not talking values. Your abstract notions all point to values.
If I had a dog chasing its tail you would be no different.
That is the thing the art is a unique placeholder. The sale or transaction is the Ethereum.
