Right, I was asking about the other half of your claim: How does the NFT provide proof of the "limited edition-ness (aka scarcity)" of the good that it provides proof of ownership for? I don't see how the NFT or blockchain allows you to verify that - as far as I can tell, that must always be a matter of trusting your company, and the process it has in place before minting things, to ensure no duplicates are ever made.
