What is it that you actually own when you buy a physical art piece? Is it the actual canvas and the paint on top? If so then that is definitely not worth hundreds of thousands of dollars on its own. Or, more likely, is it the fact that you own the original, and that the artists could never make an exact replica, unlike with NFTs? Even though you can make an exact replica with NFTs, everybody agrees on the original, and therefore the exact replica has no value. With art you could make a near perfect replica, but everybody would still agree upon the original, and therefore the original is the one with real value. IMO NFTs and physical art are still very similar.
