"Liberalism": Broadly, what other countries call social liberalism, i.e. liberty, individual rights, equality, all rooted in Locke's notion of the social contract.
"Libertarianism": An American revival of what's formally called classical liberalism. Broadly: Small government, strong individual rights, free market capitalism, etc.
Yes, its in the post you're replying too. The USA run an oligarchy system where by the vast majority of money, power and influenced and controlled by an impossibly small interconnected group.
But its ok because every four years the peasants get to chooses which billionaire is the least worse and cast their vote.
What does anything in my post have to do with liberalism?
Why can't you get decent internet in the States? Because on each location there are two or maybe three companies that collude to keep prices high. And when you try to start your own ISP, suddenly these companies offer crazy good/under cost prices so that your new ISP is unable to survive, and then jack up the prices again.
Of course, at any point, as a consumer, you are absolutely free to enter into a contract with whatever ISP you want. If only there were a few more...
Now tell me how do you fix that without bigger state imposing specific regulations.
Liberalism and libertarianism are two very different things.
Because liberalism, I/E shrink the state so that ~the corporations can rule~ the invisible hand of the market can fix everything.
Even Adam Smith recognised that you need a state to limit the power of the big actors in the invisible hand of the market.
