Mutualist Anarchism and Rationality

The derivability of Mutualist Anarchism from Kantian Morality, previously discussed, thus marks it as a model of a Rational social system.  However, it diverges from Kant's Kingdom of Ends in two respects--it is not necessarily constituted by laws, and it includes no King.  The very brief and oblique allusion to a King in the Groundwork seems to imply that the monarch in question is Kant's deity, the positing of the existence of which is justified only elsewhere, in the 2nd Critique, by a dubious proof, as has been discussed here a while ago.  And, Kant never shows that the process of Universalization entailed in the functioning of Pure Practical Reason is ever more than a mental operation.  So, Mutualist Anarchism can be conceived as a critique of Kantian Rationalism, separating its essential features--Autonomy and End-in-Itself--from its inessential legalist Monarchism.
