I also don't get it. An NFT is basically a small piece of text on the blockchain saying that you own the thing at a given URL. It doesn't mean you have copyright over the relevant intelectual property. There's nothing stopping the URL from returning a 404 at some point. And anyone can create an nft of anything, even if they don't actually own the intelectual property. It really is as crazy as it sounds. The closest real world analogy I've seen is that it's like the people who sell deeds for plots of land on the Moon.
