That's true, although most of those businesses' founders also don't have much of a choice: they aren't turning down a 6-figure pizza-delivery job or eschewing pizzeria-angel funding to open their own pizzeria. They just don't have much of a choice but to open it on their own and try to scrape by, sometimes borrowing from relatives, living with parents, getting "free" healthcare in the ER, etc.

I think it'd be a much less attractive choice if you were in an area like tech where you do have the option of a well-paying job or funding, though. Lifestyle businesses are still attractive in tech, but only if you're somewhat better off, either coming from a better-off family, having already had one minor success on a previous business, or spending some time in a lucrative job / consulting career that let you save up a cash reserve. That appears to have been Steve Blank's route as well; he became a self-funding entrepreneur only after first having a few successful exits from funded companies.

That's not true at all, there's a seed funded Indian burrito shop in Palo Alto in the whats-it-called shopping center called Tava or something.
