I never saw it as anarchy (using the popular definition), I saw it more as raw anger at society (which in part led to the philosophic musings such as what you point out) and later that anger morphing into culture jam/adbusters esque attempts to fight back against what society has become.
First time I saw it I liked it, but on subsequent viewings the violence just really turned me off.
But it's been many years since I've seen it, so maybe I should watch again and see what the current me thinks.
