Authors might as well just sell non-DRMed digital downloads from their own websites- which they already do sometimes. I can't imagine the hosting costs for that are really a problem. They can even accept Bitcoin if they want. I don't get what actual value the NFTs give you, it's not like I am ever called on to prove my "digital ownership" of the non-DRMed books I buy already.
