But lets add something: NFT's make sense for low-value consumer purchase. Buy a Lady Gaga album, and it's noted down on the blockchain that you own it. Google Music goes down? Ownership is yours still. Other stores (could be legally required to) still honor it. Possible to sell your album second hand.
Or, have the users do the transaction on one of these participating websites and create a new proof-of-purchase and revoke the old one.
Now smash that into the digitization of everything and a couple decades later we have this. Enough confidence in the permanence of tech to have manufactured virtual scarcity.
