Nothing, it's a silly talk show call in video with a bunch of hamsters trying to create an infotainment piece to feed the confirmation bias of a target audience and given your reaction, it worked.
If you want to learn about libertarianism, read the works of serious libertarians, if you want to be an ignorant sheeple keep letting videos like this one formulate your opinions for you.
Address my entire OP.
Where has libertarianism worked in the world?
Point me to a country where it has.
Been there, done that... you still don't get the fact that libertarianism
isn't a form of government nor has it dawned on you that most people in the world already operate by the
non-aggression principle in their dealings with other individuals, which means they share foundational principles with libertarians, even if they don't realize it.
Apparently the matchbook cover you received your political science and philosophy education from didn't include that part.
Do yourself a favor stop relying on YouTube to expand your horizons and pick up a book, preferably one that isn't designed to reinforce your strongly held opinions about the world.
"
Libertarianism holds that the only proper role of violence is to defend person and property against violence, that any use of violence that goes beyond such just defense is itself aggressive, unjust, and criminal" --
Murray N. Rothbard
