Hero entrepreneurs become heroes for two reasons: 1) vision, and 2) the ability to coordinate massive effort in order to achieve it. Many people have vision, but don't have influence to make a change. Many people have influence but don't envision anything ground-breaking. And finally, the vast majority of people have neither vision nor influence. It's the combination of both which is extremely scarce and at the same time extremely efficient, which rewards bright individuals who have it.

It has to be noted though, that the same is also true for people with a criminal mindset that look to game the system. It's generally a hard problem to create laws that encourage "good" heroes and discourage "bad" ones.
