I am neither ignoring the context of the article nor am I making "sweeping generalizations" or "projections". And I would prefer if you don't make these assumptions about me.
All I am saying is that signaling does not have to be conscious or self-aware in the sense of "Oh, I have to say this and that to rise to the top of the hipster hierarchy". It might just be the hipster enjoys dressing contrary to the mainstream just as the contrarian enjoys arguing contrary to the mainstream opinion. Hence my analogy: I enjoy sex. It's a heuristic shaped by my genes that would usually serve the purpose of reproduction. People enjoy signaling in the form of buying nice cars of putting on make-up: it's heuristic shaped by our genes that on average (not every signal leads to a better outcome) increases the chance of reproduction. It is not the you actively think "Okay: if I buy a car it might increase my social standing and ultimately increase the chance of girls liking me more.". You just enjoy the stuff. Just as you "just enjoy sex" or the bower bird has an innate desire to build colorful homes.
EDIT for clarity.
