I see this a lot, and I somewhat empathize with you for wanting there to be something interesting there. But what you're describing is just nonsensical. There is no such thing as a digital "THING". Any digital "THING" is only a thing via interpretation by a computer program that musts be TRUSTED to interpret it correctly. That fact makes the concept you're describing dead on arrival.
Cryptocurrencies and the very most-boring versions of "smart contracts" are the only things blockchains can do. Any time you're dealing with anything that's not:
1. Tokens themselves
2. Rules for transferring the tokens themselves
blockchain is purely worse than a non-blockchain alternative. Because you're necessarily involving 3rd-party trust, which is antithetical to the reason blockchain exists.
