Yes, the point I am making though is that if you cannot see the differences with the naked eye, or if in fact you prefer the copy if given a test, then why do you value all that stuff? Enjoy the much cheaper copy.
It is true there are unique properties that a physical original features - it is just that the value assigned to them is arbitrary, and there does not seem to be an obviously good reason to pay a lot of money for it. People do it because of what is essentially a collective hallucination centered around the idea of scarcity.
Now if there were a way to copy a Picasso perfectly, I posit that people would still assign an arbitrarily high value to the original. I mean, you can see that being the case with diamonds.
Obviously, there is something about a physical object that a digital image will never be able to reproduce. That's why people still enjoy real books, right? So I wouldn't be surprised if a real painting would carry a certain premium over an NFT. But the idea that people pay for an NFT, signed by Damien Hirst's own private wallet? I see no fundamental difference between valuing that and valuing the entirely imaginary benefit of Damien Hirst having once stood in the presence of that physical object you bought.
