Yeah, there are a lot of absolutely terrible solutions just screaming to be digitally solved that just don't get solved because the minor road bumps put in place make it juuuuust to hard to bother with the vast majority of exploits.
Look at notarizing documents. It's laughably insecure. It's just a stamp that lists a notary's name. Hiring a notary to work for you and expecting them to notarize documents for you, their boss, is completely normal and not seen as any sort of conflict of interest. Obviously a notary would quit their job rather than agree to backdate a document a day or two for the boss, right? Of course. And, despite the technical ease of making digital copies of documents or recording notary entries with timestamps or something, notaries tend to use a log book, and sometimes they just let the user fill it out themselves. In many states, the log book isn't even a requirement. And then there's the stamp. There's no standard for what it needs to look like, no secret token, it's just the words "notary public" and the name of a notary. And the names of all the notaries are listed on a public website somewhere. You can order a notary stamp on Amazon. And even if everything were impossible to fake, satisfying a notary of your identity is crazy easy. In many states, you don't even need your own ID, you can show up with someone else who has their own ID and have them vouch for your identity. And in many states the notary wouldn't even need to write down who that other person claimed to be. The whole system is absolutely screaming for digital reinvention, potentially including, yes, blockchain.
And yet, the system still mostly works just fine. A notarization is generally seen as pretty good evidence of something. People have some confidence in them. Folks you do business with will ask you to send them notarized documents. That's because most people who'd be willing to forge someone's signature in the moment aren't willing to go through the extra effort of faking a notarization, even though it's not a very high bar. And so it all somehow works, kind of. Weird, right?
