Two "extremist" political foundational theories combine to justify everything they are against

Premiss 1:

Libertarianism: https://www.lp.org/platform

Article 2.7:... We defend the right of individuals to form corporations, cooperatives and other types of entities based on voluntary association.

plus Premiss 2:

https://anticorruptionsociety.com/2013/03/30/the-united-states-corporation-a-big-plantation/

OUR GOVERNMENT IS REALLY A COMPANY AND ALL OF THE STATES, COUNTIES, MUNICIPALITIES, AND TOWNSHIPS ARE FRANCHISES

equals Conclusion:

We defend the right of individuals to form governments...

(And, by the way, if you would rather not voluntarily subject yourself to internal corporate policy, aka "the law", which includes voluntary contributions called "taxes", you must at least respect 

Article 2.1 As respect for property rights is fundamental to maintaining a free and prosperous society, it follows that the freedom to contract to obtain, retain, profit from, manage, or dispose of one’s property must also be upheld. 

which also means "No trespassing on corporate property".

And that, my Dear Reader, is how we justify Communism, or at least Socialism.

General conclusion (support only, not proof): you can justify any political system you have a mind to.
