But there is an element of uniqueness to dive into the entrepreneurship game at all. Plenty of people have ideas and do nothing at all with them. If you don't actually dive into it, quit your job, and work at it, it's impossible to build a business. Most people (the vast majority) don't have the balls to do that.

Hard work and taking that risk are necessary but insufficient conditions for entreprenurial success. You also need luck. But that doesn't discount the amount of risk taken or the amount of work put into it, and most people can't stomach that.
