I run a major music NFT marketplace and we don’t have this problem because to create content on my platform you have to be invited and go through a contract process that includes legal assurances related to rights and clearances of anything you plan to mint. Most of that content ends up being exclusive and fans love it.
That people write off the entire NFT space based on the “fakes” issue are missing the point that there are people like me who believe the technology serves the people rather than vice versa.
