No, we are talking about copying the underlying asset, not the NFT. If you could 3-D print any physical object perfectly down to the atom, the collectibility of the original item would be hurt a lot. If there were potentially infinite perfect copies of a Ferrari GTO, the prices would crash. Having a document that says "this Ferrari GTO is the original" would be what NFTs are today

This is an important thought experiment that I brought up in another comment, but my conclusion is the opposite: I think that efforts would still be made to determine which physical painting was the original one painted by the artist, and that one would still retain the value as long as the determination of originality remained well-respected. This already happens with paintings: there are extremely skilled forgeries that have fooled experts.
