But when you buy a baseball card you get a card. Here it seems that you only get a receipt stating that you have paid (aka the certificate) AND NOTHING ELSE.
If I understand it correctly, that receipt in conjunction with your keys allows you to prove you own the NFT and can control it on the blockchain(sell it, trade it, etc).
But the NFT is the receipt, if I understand correctly. You own a receipt (the NFT), and you can trade it, but why are people buying and selling receipts? You make a payment, you get a receipt, and nothing else, which makes absolutely no sense. Usually, when you buy something you get a receipt for free and then the actual thing that you have bought.
I think at that point the platform upon which the receipt resides will prevent people from making duplicates on their chain, and the owner of the receipt have control over buying/selling it.

And one should be happy to control the receipt of their purchase of imaginary goods? Ok.
If you have essentially bought a jpeg image, you have as much control over it as anyone else: Anyone can view, transmit or edit it, etc. Your "proven purchase" grants you exactly nothing extra.
