vex, you seem to be forgetting that this is the tRump century. Your ideas about legitimate power lying with government sound so quaintly old-fashioned, like that Victorians covering up piano legs in the interests of modesty; which is another fake fact. Government power, in what for the moment are still nominally free democracies, will only obtain until someone comes along with the will, guile and cash to stage a buy out. Read some Hobbes, try the Leviathan, you can see the thought processes behind the development of our modern beliefs about power. Power in its essence is neither legitimate nor illegitimate it is merely wielded.
Just in case you didn't want to sleep comfortably yu might try this piece too,
also Nigel is right re. the order/disorder thingy. Discordians have spent years mulling over this shit. Who knew we would end up on the white hot edge of political thinking?
I meant "legitimate" facetiously and in the general consensus that if power is going to be wielded, it must be done so through the government. "Legitimacy" isn't a real thing, it's just a stamp on the exercise of power. You're right that who controls the stamp at any time isn't controlled by the government itself, especially not since the government's own mass of power has been under sustained attacked for half a century. But we're not yet at the point where power can be directly exercised without that stamp of legitimacy with complete impunity for very long.
I'm not talking so much about how the system was designed, but about how it functionally works. The government does have the advantage of perceived legitimacy which acts as a force multiplier for hard power, whereas a throng of brownshirts don't. So it's the brownshirts' objective to usurp the "legitimacy" of government power in order to curbstomp their way to actual power. Just like it's every competing political or economic group's objective to ensnare the government's "legitimate" power and influence into orbit around their own. Sure, someday we might get to a point where corporate armies enact company policy despite the legality of doing so, but more likely is that they will just make it legal in the first place by influencing "legitimate" policy and removing the bureaucratic obstacles.
