I'm failing to parse your argument here. We're talking about an example usecase of zkProofs as a way to better explain the technology. We're not trying to solve the problem with every different random way to sneak into a club that you can think of.
I actually was a club owner in San Francisco at one point in time. Even went through the ABC training. Got sued at one point by the ABC cause they snuck someone in under age. No system is perfect.
But, I'll tell you that having someone show me a cell phone with my picture on it, nicely large and backlit and saying I'm 21, is a great solution to requiring people to present an ID that could come from one of 1000 places.

I agree, but I already have a California DMV app that does this. It doesn't need a ZKP.

Indeed my argument is that ZKP seems unnecessary in this example, and yes it's extremely hard for me to appreciate the usefulness of a ZKP with an example where it seems useless.

What happens when you aren't in California? Or what happens when someone from outside of California comes to a bar.

Then go find better examples if you're this interested.
