This is maybe truer now assuming the creator actually keeps a copy. It's not true in general. My wife and I are big KMFDM fans (met at a show) and wanted to buy copies of all their album covers only to discover to our dismay that many of the originals don't even exist any longer. Even the original digital copies were stored on floppy disks that someone just lost and you can no longer buy these from the actual artist or any other authentic source. I'm not sure to what extent this even matters for an NFT as I'm not sure why someone would even want to buy a signature of a thing but not even get the thing itself (in which case you're responsible for the storage). But to each their own. I've given a few grand to the local YMCA over the past two and a half years just because I'm too lazy to go through the process of canceling over the phone. May as well be setting money on fire, but I don't care. If other people want to set money on fire to buy a string of bits assigning a not legally enforceable claim of ownership to some item they never take physical possession of, let them.
