The point of an nft is to buy something wherin the protocol of the code makes it so your ownership of said object is verified as yours on the Blockchain. No need to use a middle man to verify you're the official owner (and the authenticity of said product too)
People keep thinking nfts only refers to art and games.
Nft stands for non fungible token, which a is an independent digital asset with no inheremt value pegged to it besides whatever that person wants to sell it for.
You could make the deed to your house an nft or your will an nft. The whole point is for you to be able to pull up your nft on the Blockchain and be able to go "see the address of the owner of this item is me, it's in my wallet, it's mine (so nobody else can copy it either, that's a major key, they can do all the copy and pasting they want but when that token is minted on the Blockchain ledger that's it, it's immutable, nobody can claim what's yours).
