His point about monopolies is widely misquoted and causing a lot of confusion. I think he should have been clearer about distinguishing creative monopolies and what we commonly consider monopolies, in the negative sense. There are nefarious monopolies like Comcast that are insulated from competition because of an unfair advantage. A more nuanced position should entail something like the following:

- We want competition because it allows nefarious monopolies (and other companies) to be overtaken by better companies.

- We don't want to discourage companies from attempting to obtain monopolies in their markets, since this gives them to opportunity to capture monopoly profits. Monopoly profits are not inherently bad. If a company becomes a monopoly, we want them to be a creative monopoly.

- A competitive market in the sense of having low profit margins is very different from a competitive market in the sense of whether or not new entrants can come in and compete.

- It is a bad thing if a company has monopoly power through something other than being a superior company, is capable of preventing new entrants, and is uncreative. We want to preserve the ability of new entrants to come into the market with superior products and overtake monopolies.
