Why would anyone do that with a digital asset that they want to use in a virtual world or a metaverse?If the ownership exist outside their account system then can't people just sell offline then transfer ownership? It's like if I sell you a cell phone and you hand me the cash I hand you the phone. The government can't even prove that sell went down to try and collect tax on it.
That makes absolutely no sense because NFTs are held in a crypto wallet that you own. So basically, you're saying, someone who wants to buy an NFT that I have, could theoretically meet up with me at the local police station and pay me for my wallet that has crypto related assets in it. And instead of them just buying the NFT and transferring ownership, I'm going to give them my wallet and seed phrases so that they can use the wallet how they wish. My head hurts just even trying to make what you're suggesting make any sense.
I guess, yes someone could do that, but it doesn't make sense.
