Well first of all, she stole her entire ethics from Aristotle and she claims capitalism fits Aristotle's ethics like lock and key, which is just asinine. The ancient Greeks didn't view liberty the same way as modern people do, which is an individualist cult constructed by John Locke.
Secondly, her defence of capitalism is just retarded; not only does she deny that whole groups of people have antagonistic interests towards each other and that these have asymmetric power relationships(e.g workers and owners), she also has a romantic conception of the heroic capitalist which has never existed in the history of humanity, there are no John Galts lol, they literally aren't real, and even if they were real, their ideas would be built on the backs of centuries of people before them, and hundreds of people that currently live, such that claiming they individually deserve every single piece of capital they accumulate is ridiculous.
