There's always a problem with using averages, for subjects that are innherently distributed oddly. It's definitely useful to run through examples and the average case is as good as any. But, beware assuming the average case is you, or more likely to be you. To boil this down... It may be that a founder is working for free or even taking risks for free, by continuing rather than exiting. This is true outside of startups too. Musk only owns 10% of Tesla. If the board was going to hire a superstar CEO to run Tesla, they'd probably need to give him that much equity anyway over time. So, they basically get him for free.
