No they aren't NFTs are recipts. That is all they are. They can have a connection to images or physical goods but they only proove that you bought a recipt and not actual ownership.
Sort of except it means nothing. It's like having a deed with absolutely no legal weight.
If I buy a microwave and try and return it with only the receipt they won't give me a refund because I only bought the receipt. I could sell the receipt, sure it says you bought it but I am keeping the microwave.
