Essentially, the NFT is “proof of ownership” only insofar as what is put into the blockchain is correct and accurately reflects reality.
If you don’t vet what goes on the blockchain for accuracy, the blockchain is useless, and if you do validate, you don’t need a blockchain because the validator can just use a traditional database.
It is a solution in search of a problem.
If I buy a lot of baseball cards for 1 cent, at least they don’t suffer from the oracle paradox.
NFT’s were nakedly a solution in search of a problem that weren’t even a very good solution to the problem they were purporting to solve. That’s what pisses people off.
Haven’t dealt with it personally, but know of people who have. The one constant is that the places I’ve heard of that have a RTO mandate are short-staffed and brain-drained.
That is merely a side-effect of one of the original sins of programmable blockchains - the fact that there is a delegation of responsibility of data management from a database administrator to whoever happens to have control of that data, and the controller can only manage that data according to the underlying code of the NFT.
This only sounds appealing if you’ve never actually touched a database in your life. There are too many points of failure, and said mistakes are much harder to correct.
