Those are just a couple of examples of what hackers are capable of outside of, well, hacking on things. If there are parts of problems or tasks hackers don't know, they can research them and understand how to fix them. This means that they're not afraid to jump into the deep end in other professions or tasks.
Capable of being a business person, and possessing the same drive as business people are where the disconnect occurs, in my opinion. Could a good hacker figure out the steps needed to create something that would be considered a successful business? Yes, probably so. But, are smart hackers driven to generate wealth or create large organizations of people? In my experience, the answer is often: "not really, but I'd love to help you build it."
