Is Libertarianism Moral?

Stefan Molyneux argues libertarians have been losing the battle to statists because they don't argue on morality:

libertarians have never won the argument from morality. These days, none of our opponents argue that the government is more efficient than the free market, or that communism will set us free, or that private property is theft. All the old socialistic shibboleths have been laid to rest – and yet still people support government power, because they believe that government power is moral. Most people believe that the government takes care of the poor, old and sick, protects us from enemies both corporate and militaristic, educates the young, builds us roads, blah blah blah – we’ve all heard the same nonsense since the dawn of time. All we say in response is that the government is inefficient at doing these things, and that the free market would be better – none of which touches the central rationale of state power, which is that people believe that it is good.

Our enemies understand the power of the argument from morality far, far better than we do. They constantly harp on the virtue of state power, starting in kindergarten with environmentalism, ‘friendly cops’ and the need for ‘childproofing.’ The world is dangerous, children hear, and capitalists want to kill you with smog, but your friendly government is always eager to serve, help and protect. Children first experience state power as firm, kindly and friendly teachers – so how could they see and appreciate the violence that underpins the government?

"Thou shall not steal" isn't a popular phrase among the tenured types.
