Wage labor is already very totalitarian in principle - they determine what you wear, what you do, when you eat, when you go to the bathroom, basically it's a private government of their own, and people are selling themselves into the servitude.

Libertarianism seeks to go even further with that by removing regulations and letting free market do its thing, which, considering the first sentence of this comment, would make Libertarianism authoritarian if you're not a business owner or someone rich, and the "Don't tread on me" slogan only applies to those people.
