Paintings have provenance. If you own a Da Vinci you're literally able to touch the canvas that the master himself touched. Your ownership will forever be apart of that works history, and it's yours to enjoy privately and exclusively whenever you want. It's an indulgence.
Nobody will ask you in 20 years what it was like to own an NFT, because they can all have the exact same experience by just looking at the blockchain on their device.
Humans ultimately value stories and experiences, and anything that gets work out of the way so we can spend more time having them.
The NFT is a token for the story behind it, just like the artwork. It is issued by the artist. It has even better provenance tracing than the artwork, which could be a fake.
You can see that the artist made NFTs on chain. That's actually how you can verify uniqueness as anyone can see this NFT is authentic and not a random copycat.
What is an artist sells a a print verified by an NFT. The person who buys that print wants to sell it again. They make a copy of the print and sell the copy with the NFT. They keep the original print. The NFT doesn't seem like it did anything there other than be used as deception for the second buyer. Is there a way to actually link the NFT to the thing the NFT is supposedly tied to?
That original print will probably be worthless as people will regard it as a copy. You'd also be up against life ruining fraud charges.
But yes there are ways to link NFTs to products. Louis Vuitton and Nike are linking NFTs to their products with things like built-in NFC tags and QR codes plus other probably more secretive things.
