Second, I would ask the author which form of capitalism he was critiquing. Is he referring to Mercantilism, Free-Market Capitalism, Social-Market Capitalism, State Capitalism, Corporate Capitalism or a mixed economy?
For each is a distinct form with their strengths and weaknesses. Many have been created to address the weaknesses in others. Weaknesses that can be seen in the "rules".
And if the author is unprepared to discuss the various types of capitalism or tries to claim that they're all the same.....well there isn't much point for further discussion because any opinions he has will be influenced by his lack of knowledge rather than any real substantive issues.
