Disney would DMCA the NFT marketplace, like OpenSea or whatever. It's happened before, although I'm not sure if Disney specifically has done it or not.
What if there was no copyright material associated with the listing?
If you don’t actually present an image of a Disney character on the site, there is nothing preventing an NFT referring to one.
I think you might be right - it’s worth a try!
Until you have to defend yourself in court. Then it might not have been worth it.
Defend yourself for what? Posting a url with a hash attached to it?
OpenSea does delist nft's for DMCA issues. They require folks filing DMCA requests to fully dox themselves to keep competitors from griefing projects that aren't violating anyone's copyright, but they do respond on it.
