Point two seems to be talking more about micromanagement specifically, but I wouldn't be surprised if it's more the issue that people who like doing don't necessarily like leading.
Another reason that I think is missing here is when a person that should be a leader has a very liberal mindset that comes with a reluctance to tell other people what to do, regardless of ability (skill + confidence).
