The goal was not that "everybody knows your name"; only that one's identity be well-known enough that it will not be forgotten, or at least (in this particular case) be rediscoverable. So the point is not undermined at all.
I don’t generally like obligatory xkcd references, but this one is an exception. I like how it reminds us that our experiences are not universal, and people have all kinds of experience spatterings, even if we may come from a shared cultural background. And, instead of the inclination to feel superior to someone who doesn’t know a thing, we can instead feel pleased to share our beloved cultural touchstones.
