According to Immanuel Kant's doctrine of right, the existence of a state is required to establish a condition of equal freedom for all. In this condition each is free to use her person and property in ways consistent with everyone else's similar freedom. In the absence of a functioning coercive state that specifies who is entitled to what property, no one has determinate rights; there is no clear “mine” and “thine”. The state enforces a set of rules binding on all that partly establishes and partly constitutes a condition of equal freedom. People are morally obligated to cooperate with others to create a state if no effective legal order exists and to cooperate to sustain an existing state that rules them, even a very defective state.
