If one describes politics to mean the system we're operating within now, then yes, I think that you're correct.
Of course I agree that the current system is a corrupt, clown show, parasitic disaster.
My argument is that politics describes all systems of human organization. The problem I see is when people say "I'm outside politics" but mean "I'm outside the current system" or "I'm outside those politics", they then (consciously or not) cede their political power back to the current system. The current system is an instantiation of politics, acting through debased and corrupted elements of human nature.
I see Bitcoin as a way to reverse the debasement and corruption of human nature, to realign politics more closely with positive elements and away from corrupted elements.
So yes, maybe I'm being a bit pedantic. And transcendent language does have a place at the beginning of a movement to inspire and motivate. But after a point, when the movement is no longer a fringe revolutionary movement and is more of a "real player", then the separationist rhetoric becomes a problem, potentially enervating the most vigorous fighters at just the time they're needed.
I believe that it's now time for that rhetorical shift - we're not outside politics, we're building a new politics outside those politics.
