Fine artists who are known in the international art market do not take commissions. They also do not give buyers of a piece copyright (obviously both of these things are even more true if they are dead).
You also wouldn't be able to distinguish a fake painted for a few thousand dollars, much less so with a print or digital art, so the physical artifact is somewhat meaningless as well, at least as far as value goes. Collectors buy pieces and keep them in storage. They might buy a piece without ever laying eyes on the physical artifact.
The art market has always run on provenance and certificates of authenticity. You could argue that fine art is bullshit, and you can also that a blockchain is not necessary to keep track of certificates of authenticity, but arguing that the entire concept of art ownership without copyright is bullshit is to ignore what the reality of the art market has always been.
