The answer is "no". Even the idea is idiotic, you want an ordinary database, tying yourself to some crypto infrastructure has zero benefit over just using a regular database.
The blockchain is a database that's better than a classical centralized database for an application where data accessibility, integrity and transparency are of paramount importance.
The answer to "could crypto help to..." is always a no.
It is just a unmodifiable p2p public database.
Yes, keep trying to make problems for this non-solution. I'm sure you'll find one eventually.
