I don't like speculating on NFT's at all, I think most will go to 0.
Another point I just made to him is "What if a famous artist released an NFT collection, would they be worthless?" What if da vinci, or banksy, etc, released an NFT collection? People would value them. They would retain their value and appreciate, actually. Doesn't matter that they can be "copy pasted", there's still digital provenance attached to the originals, there's still true ownership.
