You guys are approaching this from the wrong direction: you've taken NFTs and decided they are valuable, and set about trying to prove you can do useful things with them.

All of the things you've mentioned already exist, with a lot less effort. Copyright law is well established on digital goods. Contract/IP law is well established.

If NFTs have utility, beyond greater fool theory, then surely it will exist beyond having to go replicate all of these web2/tradfi/whatever concepts. Otherwise, what's the point?
