I wonder why in HN you usually find comments of excepcional quality except when it comes to crypto. A NFT doesn't enforce property, humans do. A NFT it's only a token that can have an arbitrary meaning, but with the warranty that all transactions done with that token are legitimate. So no, you can't steal a digital asset merely being the first to mint its NFT, because if no one recognizes your property no one is going to buy it from you.
