You mentioned some good stuff but personally think this is more nuanced than someone being "too cool" for other people - of course that can be a part of it but not always, we're all different.
It is certainly nuanced, and one can argue that behind the isolation is a defense mechanism of one who does want to engage but is fearful for however many reasons. It could be shyness, masked by an ego that won’t allow them to be vulnerable (hence the ‘I’m not shy or scared, I just don’t want to be bothered’).
Or it could be resentment. I’m kind of weird, and say weird things, and often entertain weird ideas and say weird shit. I’m tired of being misunderstood for the n-th time. How about I just keep you all at a distance?
But ultimately, most importantly, it could be that life is not that serious. Hence the too cool for school.
Everyone from time to time has a reason to take a step back, no big deal.
