> I think it's more an economic incentive for digital creators
I don't understand. NFTs are not hooked up to the legal system of copyright, so how is it ensured that the "digital creators" are the ones that are rewarded? If you create an amazing image, what is to stop me getting the original NFT (by doing something like mining it? sorry I'm not familiar with the terminology) before you do and selling that on without rewarding you? Or, even if you did make the NFT first, what's to stop me altering one pixel or some irrelevant metadata of the image to allow a district NFT being created and selling that instead?
Another commenter said that NFTs are (sometimes? usually? always?) not even derived from the work itself but simply some URL that points at it. That crazy! What's to stop me making another URL for the same work (either hosting it separately or just redirecting to your URL) and making an NFT for that? What if my hosted version outlives yours? The whole idea is so totally ludicrous that I don't see how it's gotten this far.
Unless there's something huge I'm missing (which I'll admit is possible), it's obvious that NFTs are totally useless for this goal of rewarding digital creators. Traditional copyright, while flawed, at least makes an attempt at rewarding the creator of the actual work.
