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.
