A high quality photo print and frame costs quite a bit of money. That's maybe a couple thousand dollars. And then the artist hangs them in a nice gallery, with sales people. That costs more too. And the final price isn't something like 100x the cost, it's maybe 10x if lucky, often 2-3x.
And again, you can't really reproduce it easily. If I found some really high quality scanning store, I could do a decent job. But it would cost me a lot of money, and the signature on the print wouldn't look or feel real.
So again, big difference, and already we have to admit paintings > prints > digital images.
You absolutely cannot have a perfect copy of a Picasso. Sorry, that's a meme that's not real. You can carbon date the paint. There are ridiculous complexity in his layering techniques. Even the specific paints he used were from his era, and hard to find. It's physically provable to show a Picasso is a real one that came from his hands. Not possible with an NFT as there literally is no original. You can prove the coin is the coin he made, but that's simply not analogous.
