This is an important point that demonstrates two things. First, that if you really care about what you're buying, you'll make sure what it references points to a content hash and not a URL, and you'll pin it yourself. And second, that if you have to store the image yourself that you paid for a pointer to, you've wasted your money. I'm a fan of cryptocurrency, cryptography underlying the internet, even the concept of a one of a kind, non fungible token is interesting and I see how it could be useful. But all this web3 stuff and in particular the hype with which the NFT concept is being marketed to sell useless shit are things I'm not a fan of.
