According to Libertarian beliefs, the government should be as minimal as possible so as not to interfere with the workings of business. But how do you then prevent monopoly capitalism under a minimalist Night Watchman State?
The answer is: you don’t — which is “working as intended” to a libertarian. Both because their contempt for the government is so great they would sacrifice our very national treasures if it meant squeezing another cent out of the public coffers, and because they are fans of monopoly capitalism. Greed is good, and “competition is for losers” (according to tech billionaire Peter Thiel) — so what if the invisible hand must be made to slap around the little guy?!
Money is a religion, and these people are True Believers.
