i think the main motivation for statism - the basic reason we human beings have been state-ridden and state-addled for some centuries now, eventuating in hundreds of millions of deaths - is sexual. the state might be based on a social/sexual contract, but that in turn is really based on a rape fantasy. some people want to tell other people what to do, say, believe, and how to die; most people just want someone to tell them what to do; they associate that with orgasm. the history of the state is the history of bottoms chasing tops. one pretends either way to have goals, or be aiming at human welfare and happiness, but really it's an intrinsic lust to be subordinated, concealed under thousands of layers of jive-ass yipyap and absurd iconography, amounting in all to total self-delusion about our motivations. i wouldn't go around hoping for much future for a species like that, or spend much time pre-mourning its passing.
the other (connected) impulse that leads to the state and other derangements is the crushing burden of loneliness. we yearn to merge and so we invent and subsequently enforce collective identities. we are social creatures, as many have remarked, usually leaving out the proper modifier 'desperately.' for the masochist, this is a longing to disappear; for a sadist it's a longing to subsume everyone to the self. we want to be food-processed into a human soup; we think that will cure us or something. so you first 'detect' the allegedly pre-existing identity (like being an englishman or a savage or a proletarian, etc), creating it by other-extrusion; then coerce people into simulating it. i have a feeling that hasn't cured us after all.
