On the contrary, your sentiment reads less like wisdom and more like hardheadedness. I am glad there are plenty of others here who do not share such a narrow-minded sentiment.

The venn-diagram between cryptocurrency and ZKPs is not a circle, or really even close. They're a mathematical concept first and foremost, and thanks to crypto dumping tons of money into the scaling problem, now much more easily worked with in code across any application. So much for all cryptocrap being, well, cryptocrap!

Your example is terribly contrived. No, you won't replace your drivers license with a ZKP. But a service might validate that you're of age, or meet some other criteria, without you(or they) revealing actual information about yourself.

All of the examples I gave(none of which are my own, but from other commenters who are I'm sure happy to discuss further) require the context of established trust. "Classic asymmetric systems" have problems with this.
