And once again, no. Historically, capitalism has formed itself through colonialism, enclosure of the commons in combination with various laws limiting the movement of individuals on their own while allowing for mass movement toward the factory floors, slavery and genocide, despoiling our lifeworld for every morsel which will bring profit, as well as the social appropriation of people's bodies toward the institution of work. (Sylvia Federici's _Caliban and the Witch_ is definitely worth the time spent reading it!) This is the basis upon which capital has been, and continues to be, accumulated in repeated cycles and in various forms. Think of the first colonization of Cuba in 1492, and the very recent 'normalization' of Cuba. Very different methods of 'primitive accumulation' and opening new markets, but a ready to hand example of this cyclic accumulation.
'An-' caps will look at the above features of colonization, genocide, etc., and say, with varying degrees of sincerity, that these are all products of 'the State,' the principle dark fallen angel of what could be a light, heavenly, civilization. Theirs is a Manichean worldview in which 'caps always try to conceptually separate these undeniable violent acts and features of modern civilization from what they see as the 'peaceful' or 'voluntary' exchanges of products and services; in their parlance, 'the Market.'
Therein lies the mendacity which is idealism; ideology, particularly **their** ideology.
The accumulation of capital didn't, and doesn't, simply rely upon 'the State' and/or 'the Market,' on 'force' or 'voluntarism,' in some divine dualistic plan. The accumulation of capital has relied upon a wholesale conversion of every living human and non-human into a quantifiable commodity. This conversion relied upon the work of the churches, the schools, the newspapers, novels, the arts, the philosophers and scientists, every bit as it has on gunboats, cops and politicians, and always in tandem with these latter openly coercive institutions. They are, and always have been, inseparable, where the 'internal' and the 'external' aspects of every unique one are dominated by these spooks.
'Caps will always shake the blame and point the finger at the spook called 'State,' and see themselves as offering 'opportunities' and 'choices' while ignoring the conditions within these choices are made, particularly when it comes to previously colonized, enslaved peoples. Their Manicheanism blinds them to the reality of the forced conversion to internalized, (anti-)social capitalist relations as well as the alienation of body and world now simplistically conceptualized as 'labor' and 'resource' respectively.
Even their own Manichean worldview is out to get them at the end of the day, for a futuristic anti-topia of an absolutely voluntaristic, global Ancapistan will either be founded directly through violence or later in the wake of that violence when the conversion is completely socialized and internalized by every unique one. Labeling this violence as 'the State' is as wholly mendacious as it is irrelevant, for either way, Ancapistan is a deadly and devastating project through and through no matter when it's believed it will to come to pass.
