members of a subculture gain a perceived glamour, which incentivizes outsiders to come in for superficial reasons
It has a real cost to the original members, in terms of their loss of immediate credibility. You see a guy with sailor tattoos. Did he serve in the Fleet, does that speak to his work ethic and skill with a chart or a diesel engine? Or does he work in advertising and drink soy lattes? You see a girl with thick-rimmed glasses. Is she an old-skool assembly hacker, or did she just think they would look cute with her "vintage" dress? It means the genuine people, who have paid their dues, need to prove themselves over and over again to everyone they meet. That is why everyone hates hipsters.
I don't think that's actually true; otherwise how would they be a part of a community with other like-minded people? How would they authenticate themselves to one another? Hell's Angels are another good example.
