For over a century and a half, anarchists have been arguing that coercive, hierarchical organization (as embodied in government and corporations) is not equivalent to organization per se (which they regard as necessary), and that coercive organization should be replaced by decentralized, nonhierarchical organization based on voluntary cooperation and mutual aid. This is hardly a rejection of organization.
