Right, I doubt many countries would legally recognize NFT, and there's no software mechanism for enforcing ownership too. It's pretty much the same as selling Moon land or some distant stars - a pointless record in a database that has no real life consequences. The fact that so many people are jumping this bandwagon just shows how speculative and irrational the crypto sphere is, and how there's a lot of "dumb money" - probably some early ETH investors who now sit on millions worth of ether and don't know what to do with it.
Im not understand too, how about if Jack Dorsey's tokenize his tweet in another NFT platform? Can the first buyer sue that issue?
The battle bid between Estavi and Justin Sun also irrational with The highest offer is $2500000 by @sinaEstavi.
