There's a guy who has been selling property on the moon[1]. This is exactly the same thing.

It doesn't matter what you think ownership is. We're redefining it. :)
See you on the other side.
All intellectual property law works this way already. The copy you have does not have any bearing on the copy someone else has, but we created laws that link it back: you don't "own" the copy you have, and using it in certain ways is made illegal.
NFTs as they are now, without any legal protection, are still innocent, but they are bought because people want to "own" something. Since NFTs don't actually provide technological means to implement that "ownership", the next logical step is to declare it by law: "owning" an NFT gives "ownership" of the content. I hope it never comes to this.
I’m pretty sure my domain name NFTs give some ownership rights you are overlooking.
In other words if I own abc.eth and abc.com and sell them both to you directly but I keep the abc.eth NFT and keep abc.com, then you could still bring me to court to enforce our agreement
