This is the one place where NFTs make some sense. Ideally, such an ownership mechanism would be open and not tied to the lifespan of a particular publisher - something that's hard to achieve in practice without a distributed system like blockchain.
I wouldn't say NFTs per se, but I do think a blockchain could help here. If you can point to a specific block that documents that you purchased a copy of a piece of media, you should also be able to transfer that block to another person.
