Market anarchists, like all anarchists, start from the assumption of ordinary people encountering each other as equals, and deciding without coercion how best to work together to meet their mutual needs. This may be by exchanging the products of their labor, by producing cooperatively or by sharing. The main thing, as anarchist David Graeber has argued, is that whatever forms of organization emerge will do so through an open-ended process of interaction among equals, in which no party can call on armed force to compel others to obey their will.
