I. Introduction

A common misconception among those who regard the liberty movement from without is that it is composed of people who all see eye to eye on all, or even more, issues. However, the beauty of this movement that is currently sweeping the nation is that it is less a group of people who adhere to any certain ideology, and more a coalition of individuals coming from a vast array of standpoints, but who all understand the damaging nature of government and the value, whether intrinsic or pragmatic (usually both) of freedom.
Many “libertarians,” in identifying themselves as such, simply do so out of simplicity. The fact is that ideal types can be deceiving, as they can cause one to be prejudged due to a political label, but are sometimes necessary in giving a brief synopsis of one’s viewpoint.

The group of people who refer to themselves as libertarians also due so simply because despite their differences, they understand that some unity is necessary in order to be any kind of cohesive force. If mutualists, anarcho-capitalist, market anarchists, left-libertarians, libertarian republicans, classical liberals, voluntaryists, agorists and the like all split up into their own separate groups, they would wield little to no influence on the political stage. Thus we have seen the rise of such organizations as the Campaign for Liberty and the End the Fed network, both of which are comprised of people spanning much of these spectrums.

II. Left-libertarianism (see the full article)

To be clear, left-libertarianism does not use the term “left” in the same way that it is used in modern day mainstream politics. It instead refers to the leftist tradition of classical liberalism and anarchism (a classic example would be the leftist revolutionaries during the French Revolution who favored free markets and liberty from the absolutist monarchy that had dominated France for so many years.) Essentially, libertarian has historically been a school of thought that has countered political authority. Left-libertarianism is sometimes also referred to as market anarchism.
