Had thoughts like that before, someone pointed that it already exists and is called C2PA - no blockchain necessary. It’s not yet widespread, though.
As for NFT, when it came out I had thoughts that it could be used for completely transparent and automated businesses. Something like an AirBnB with a digital lock on the front door and you could buy an NFT for a daily stay that you could use to unlock said lock. But then if there’s only one company that accepts said NFT’s then there’s zero reason for it to be on blockchain, they can just send you the code, and if they scam you there’s no use for either NFT or the code. There could be real estate ownership certificates, but then again, there would always be only one authority issuing them - zero reason for blockchain. There could be like crowdfunding NFT, but then again, there could only one party managing the funds. There were tons of ideas for practical usage of NFT’s, but all of them hinge on there being some party linking the zero-trust crypto and the real world, and if there’s only a single trusted party then it always makes more sense for that party to deploy a normal database in place of blockchain and just provide an API endpoint to verify ownership.
