The reason libertarians can mock the political system, and the reason libertarians can never meaningfully participate in it is, libertarian philosophy is beyond politics.
Websters defines politics as; activities that relate to influencing the actions and policies of a government or getting and keeping power in a government.
A famous author once described politics as; the art of obtaining influence and power without actually earning them.
The two most important words in both those definitions are influence and power. The seizing and wielding of both.
Libertarians can envision a post-politics world. A world where free men and women aren't led, aren't ruled, or governed, by anything except the principle that once emblazoned our first national currency "Mind Your Own Business".
These words today are often seen as a cruel retort uttered when someone raises questions beyond the pale of propriety.
But, they have a deeper meaning which is, that which truly does not involve me is not my concern. Living my life on my own terms and asking that no other man do any differently.
This simple moral creed is almost impossible to live by because, at heart, most of us are a herd animal. It doesn't matter if we are a staunch supporter of Democracy or a serf in a Soviet gulag, we cannot keep our runny proboscis out of other people's business.
A Libertarian Society could never truly exist as long as we still believe that we are both our brother's keeper and his jailer.
