right, my objection came more from you making it seem like extremism=authoritarianism, as if libertarianism isnt an extremist idea.
the second paragraph was mostly me having a bit of fun, though tbh i still dont see how a cirular political model holds any merit except that it gives one the ability to say: “look at those extremists, they are all the same!”
extremism isnt an objective thing though, just like centrism, its always dependent on the overton window. thus imo trying to tie any meaning more specific than “outside the frame of common political discussion” to extremism is a fools errant.
besides that, i think we simply speak on different terms. with “libertarians” i refer to both left wing and right wing, while your last post indicates to me that you are specifically talking about right wing libertarians (i.e not anarchists) correct? in that case i agree that this form of libertarianism inevitibly leads to rule of oligarchs.
