I'm not convinced his explanation is correct. Power laws appear in many places besides economics and biology. Even in places where there is no concept of competition. For instance, the distribution of word use in the English language follows a power law. Words don't exactly "compete" for use and there is no reason to expect a power law there. It seems like they appear almost everywhere. I have yet to find a satisfactory explanation of why!
