The artists are better off using a central marketplace that issues certificates of authenticity. They don’t need a blockchain. That way they don’t take the risk of holding xtz. Tezos is not decentralized by any stretch of imagination and there is no guarantee that the certificates will last forever

I didn’t make the case for hodling xtc. And I am not aware of an open centralized digital art market, which has a community of liquid art collectors.
I am also not making the case for Tezos, but rather promote the experience of a working digital art market and ecosystem, which is technology agnostic and will embrace happily any technology that serves the purpose.
My skepticism stems from people (not you, necessarily) inserting a blockchain and token wherever possible, when the same problem can be solved in a far more cost and compute efficient manner. That plus my original view that a certificate of ownership for a digital image doesn’t make sense (because of 100% fidelity infinite replication)
