not really sure what you mean by "unnatural systems", but nfts are just a way to represent a unique thing on a blockchain. EIP721 defines the interface to this unique thing. It's nothing more than a set of functions that enable you to transfer it to another account and approve (and revoke) operators to manage it for you. what makes nfts "good" or "bad" is how it is getting used. I'm implementing an order-book based dex. Every order is a unique thing, implementing ERC721 adds that extra bit of standardized functionality.
