These paintings sound almost perfect for an NFT art project (burn it and turn it into digital tokens), given that the quality of the art pieces is not super high, but there's huge cultural resonance. To be fair the idea is much older (Yves Klein, the Klein blue guy, Zone de Sensibilité Picturale Immatérielle [0]).
I regret making that comment, even if right now the NFT craze appears over I'll have nightmares if it comes back and someone starts burning Bob Ross paintings (or anything else really)
I think NFTs have no credibility in the eyes of the public. Something akin to NFTs tracking real world ownership of physical things could work, but we already have that in the form of registries and deeds. Provenance is a solved problem, from a technical and social perspective.
The idea of “owning” a purely digital asset that anyone else can just make copies of (but not “own” according to some blockchain) just seems silly.
