But not everybody fits into that model. I think most bootstrappers would love to build a company which provides them with a passive revenue stream.
More importantly though, you're right - its about extra space and better control not infinite space.
I'm just saying: the existence of shared hacker spaces doesn't make YC more viable if VC collapses, and you have to account for the fact that many people (most people?) will pay attention to money when it's a 3x-5x difference.
It's also not that easy to get to the point where a business is making you 40-50k/yr, even though that number sounds low.
If your family understood your dreams and was willing to support your ambitions and was ultimately willing to eat Ramen, anyone could make use of this model.
i don't assume we shouldn't exclude the middle, except that's where a wealth of experience and wisdom comes from.
