It can be "an NFT of that person". The NFT is the contract and the image, name and descriptions can be considered metadata. I think you're unnecessarily picky here: Strictly speaking, you're also not buying "a song of the Beatles", you're buying a copy/recording of an encoded piece of convoluted sinus waves or whatever.
