Libertarianism isn't a form of government. You can't compare Libertarianism to a democracy, republic or any other form of government. That's like comparing the taste of an orange with the taste of fulfillment. They aren't even in the same realm.

Also, passion is at the heart of the force. Love, desire, gratification, courage, shame, fear and countless other emotions are how you connect to the force. The Jedi, however are responsible. They embrace the emotions but control them, ensuring that they never run out of control. The quick and easy path, is to let the emotions rule you, to do everything you want, to experience it all and damn the repercussions. You want that lollipop in the baby's mouth, take the damn thing. If the baby wails... so what? The lust for power is just another lust, and with power one can slake yet more lusts and never again feel the pain of unfulfilled desire.

This is the true nature of the Dark Side.
