Don't sell the food; sell an NFT of the food. That'll -really- up your profits. Plus, NFTs never spoil!...until you add that feature. Once you have spoiling half cans of tomato sauce in the metaverse you'll be rich!

NFTs with expiration dates! Thanks for making me a billionaire.

You joke, but that's exactly what domain names are.

Domain names come from central authorities. Transfers are reported to the registrar.

Regardless, they are non-fungible tokens with expiration date.

But if you really want to be extra pedantic: the Ethereum Name System is a domain system running on the blockchain, and each domain is a NFT with an expiration date.
