The domain name is a human-readable address to digital content. It also has some added value in that purpose if it's shorter, easier to remember, etc. An NFT is not an address, any link is purely abstract. The NFT could go away and not impact anything it's supposed to be linked to. In fact sometimes people make a point to purposely destroy the thing abstractly linked to the NFT. Those seem very different to me. In fact even if you wanted to use an NFT to be the address of a piece of digital content, you couldn't easily do that: You would need to build something like DNS on top of NFT's in order to make them human usable in that way.
