You seem to know what you are talking about, so I reckon you are the person to address such questions to. I would appreciate anybody else answering them, of course, and since this is quite a lot, I certainly do not insist anybody actually sates my curiosity. I may attempt to google the answers, but half of what I find reads like a sales pitch while the other half is too esoteric for me to figure out.
NFTs may represent ownership of a particular thing, but is that ‘ownership’ legally actionable in any way? If I buy an NFT of a drawing or a song, what are the practical implications of it?
If I have a deed to a car, it now means that I am to do with that car as I please: sell it, crash it, paint it, drive it. If I transfer copyright for an artwork from an artist to myself, I can then do with that artwork as I please: sell it, change it, use it as an asset for a game, issue takedown notices to everybody who reposts it. This all will be recognised by the courts should the question of whose thing it really is come up.
But, if I own an NFT, what do I actually have, other than bragging rights? The artist still has the copyright, and anybody can right-click and save whatever that NFT is pointing to. So far, this seems like a digital equivalent of ‘naming’ a star, which is quite an amusing scam enterprise on its own.
And, for that matter, where is this ‘proof of ownership’ actually stored, and can the infrastructure keeping records of it go down without any trace of my NFT ever existing or belonging to me left? How this actually is realised depends on the jurisdiction, of course, but a deed to a car or a copyright transfer agreement are represented in notarised paper documents and government bureau records. Thus, I have something tangible that holds the proof of my ownership, and my ownership is also registered elsewhere stable.
But, as far as I understand, the records of these NFTs are held on online platforms, so what I am to do if a platform goes down? How do I ‘hold’ an NFT then? And, how do I prove that it points to what I think it points to?
