There's nothing false about the distinction between working for someone and being an entrepreneur. They're extremely different. One is financially low risk/low reward and the other high risk/high reward. I don't think it's cowardice to choose to get a full time job, but it definitely is brave to turn down a high salary and start a company, when you don't already have money.

Your examples are of people that want to do other things, more so than being an entrepreneur. Those people obviously should do whatever makes them happy. For the people that want to be entrepreneurs, above those other desires, there's nothing worse than getting a regular job.

The world is full of people who wanted to be entrepreneurs, but got tied down in full time jobs. Some of those people manage to break free, but as a percentage it's probably quite low.
