I think it should go without saying that scare quotes are implied any time I use the word "academia". People today, as surface-level and uneducated as we are, recognize that modern academia is a joke (on a much simpler level than that which you've expressed--Boy my head's spinnin' readin' all that!). And that is precisely why so many people try to eschew the idea of transcendental art or revolution. Because those ideas have been themselves reduced to pretentious dogshit by academics. Academics are the new aristocrats. We are not them. Revolution and transcendence are matters of personal responsibility at this point, not grooming. "But why bother expressing anything at all in your simplistic, muddled way, then?" Because expressing and publicizing one's hyper-individualized, post-community college epistemology is just a normal part of being a social creature (APE) and hoping to earn a bit of snack machine money in the process.
At any rate, I'd still assert that noise is now a well-enough recognized phenomena of popular culture, and has been since the early 90's at least, entirely outside of academic circles (From what I can see, noise only became de rigueur in academia again in the late-90's, not surprisingly after it appeared on MTV and started seeing releases on "popular alternative" labels [i.e., Relapse/Release]), and is therefore just as ultimately meaningless as anything else that lacks purpose without being given a hyper-individualized context. It's become an Internet meme.
But fair enough: Noise is not "pop". Still, it's passe. It's been through the wringer. It's just another idea scattered on the pile for us magpies to pick through. Find your niche. When it comes to art/philosophy FOR average, everyday people (I'm talking about people like myself: Everyday denizens of the Burgerpunk Dystopia, not the have-read-a-whole-book-ever-people, who've been more than indirectly-by-way-of-Wikipedia exposed to abstract philosophical concepts), we're all cultural magpies. We all have a lot of surface-level ideas and understandings of things, and not many particularly strong foundations. Everyone is disconnected. And so, we find a peasant-grade, cobbled-together, cult sense of culture, spirituality, meaning, etc. We're all just normal, uninspiring, frail, stupid over-smart animals stumbling through the Rubbishxe2x84xa2 here. It doesn't matter if it's Classical, white noise or M1 piano riffs. It's all there: a buffet of centuries-worth of art and culture and concepts and philosophical debris, all tangled up and waiting to be repurposed into a million little perfectly-individual, but ultimately hollow worldviews. That's the world us painfully pedestrian, lazy, apathetic, underprivileged Juggalo-people have inherited. That's really all that people require these days, for better or worse.
I'm content to make the best of it. But, for as much as I talk about being one of the unwashed masses, the truth is, while I'm not so intellectually distinct from them, I'm not well-integrated with them either. So, maybe "noise people" are fringe cases. Just like serial killer-cannibals and pedophiles and functional alcoholics and people who cut themselves and people who watch anime who can hide it well, we blend in. The interest in, enjoyment/intrigue, etc. of noise is not necessarily "mainstream", but for a maladjusted peasant, it is still little more than a pleasant distraction that seems about on par with any other vanilla perversion. So, why is that such an unsatisfactory answer? I guarantee, you'll be hard-pressed to find a better explanation for "enjoying noise" past the age/mentality of limp, angsty teenage rebellion. I'm curious if, maybe, you'd like one. But I really don't think you'll find it. Frankly, I feel like you're wasting your time on us. I feel like I've told you as much before, even.
