I'm not necessarily an NFT proponent, but to be fair, you can also duplicate art in the real world. Forgeries and replicas of the Mona Lisa and other famous art exist, and are sometimes so good they fool museum curators for years. Yet, they're almost worthless compared to the original. Why?
Reproductions are not "worthless" by any stretch of the imagination. They are worth less than the original but this is easily understandable. It's because they are not the same thing. On the other hand, digital copies are exact to one another and also mass produced by a machine (a computer) and thus not having a different "story" that could set them apart.
