What makes monopoly a monopoly:

If you are a monopoly and then you do something to maintain that monopoly or to extend your monopoly, that's what makes it illegal. Like, if I just create a new product category, some widget that no one's ever heard of before, and I start making it and it's popular, I'm by definition going to have a hundred percent of the market. That’s not illegal.

What would be illegal is if I had a hundred percent of the market and then I said to my distributors: “Hey, if you want my thing that everybody wants, you can't distribute my rival's thing.” That's what turns it into an illegal conspiracy.

About connection between authoritarianism and monopolies:

John Sherman, of the Sherman Antitrust Act, said that if we will not be ruled by a monarch, we should not be ruled by an autocrat of trade. He was very explicit about the link between monarchy and authoritarianism and monopoly. And they were using the term monarchy because fascism hadn't happened yet, but monarchy did exist. In the 19th century, Americans were looking across the ocean and they were seeing a bunch of kingdoms. There was a little bit of democracy, but that's what they were really looking at. And they were like, we don't want that.
