1. You mean copying the image that the NFT points to?
The copyright of that image still exists even with the NFT. So existence of NFT doesn't change anything about the picture's copyright. With or without NFT you can not sell prints of the image or use it however you want without permission of the copyright holder.
2. You mean copying the actual NFT i.e. somehow taking over the block in the chain and assigning it to you?
That is a kin to stealing. Why does it matter if the property is digital or physical? This is the kind of mental gymnastics kids use to justify their pirating of entertainment. "I only *copied* this album, I didn't steal it, the artist still has theirs" is such 14 years old's take on the issue. If you don't want to pay for the media you are consuming then don't pay, but then you also shouldn't consume it. This kind of take just shows more how some people haven never created anything of value, yet they want to extract every bit of value from the society.
It sure would be nice if we lived in a world where copyright and patents weren't necessary, but people try to take advantage of everything and anything, so to protect innovation and creativity we need copyright and patents.
