I think OP understands there may not be a physical difference, but the provenance / "Colour of the Bits" is important to them; and that's a valid position to take (not the only valid position to take).
For example, a woolen blanket made by my mother is much, much dearer to me than an equivalent woolen blanket made in a factory.
I see it very likely that certified-provenance human-art may command high prices in the future; but also for physical part, it's pretty trivial and doesn't have to be so posh and fancy - anything from street art to art galleries and art collectives/workshops.
This is already the case for the most part. I don't think anyone expects AI to displace "name brand" art. Low quality and stock art will become profitless virtually overnight, while artists that already make good money for original works will likely continue to do so. Your blanket analogy is apt for that reason. Human made blankets are indeed more special and people do often pay higher prices for them, but the vast majority of blankets sold or in use were made by machines at this point.
> I don't think anyone expects AI to displace "name brand" art
The problem isn't for existing artists (except in terms of ethical issues)—it's for new/budding artists, who will have to contend with challenges to the authenticity of their work. How can they prove that they put their blood and sweat into making a piece of artwork by hand when an AI could've generated something equally passable?
The woolen blanket is not a precise example: you like one more for sentimental reasons, but you agree that both are blankets. If you had said "I don't think that a factory-made woolen blanket is really a woolen blanket" the discussion would be different.
> If you can't distinguish between human-made art and AI-made art
The art is always human-made. Missing attribution doesn't mean "machine made it". Humans developed the AI, ran the AI, created the training data, picked the non-horrible sample from the output, etc.
For example, a woolen blanket made by my mother is much, much dearer to me than an equivalent woolen blanket made in a factory.
