He says a lot of things that are going to make a lot of people mad because it goes against the things they want to be true. For example, he thinks competition between firms is wasteful and that business owners should seek to build a monopoly over something.

He substantiates this view with what's in my opinion quite lucid reasoning gleaned from his experience both founding Paypal and his later exploits like Palantir. But it will be insufficient to convince many.
