"Cooperation Is Libertarian
The Cooperative Movement is founded on the principle of voluntary
association. Any member may withdraw from his Cooperative, taking with him
that which belongs to him. In other words, he is free, in that respect.
And, since the ultimate aim of the movement is the gradual disappearance of
monopolistic and compulsory institutions, the individual will enjoy a
progressively larger freedom than he does now, if this aim is reached. A
cooperative association can tolerate criticism; it can be threatened by any
member with non-support, or even with opposition; any number of members may
actually secede and be free to start a counter organization, without being
shot for treason. In fact, a true cooperative is a creature of its
members; it has no power over them except what has been accepted by
voluntary agreement; they can overthrow it at any time; and it will only be
able to exist if it gives the service for which it was intended. This is
freedom; and, because cooperators acknowledge this freedom, there is hope
that, in the course of time, they will acknowledge freedom as the most
important requirement in all the relations of men. Moreover, they will, no
doubt, also find that the only liberty possible in human relations is equal
liberty -- that is, the largest amount of personal liberty that is
compatible with the like liberty of all."
