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.
Just because you are in your mid-30s and have a family doesn't mean you can't be thrifty. That's a lifestyle choice. Nobody has forced anyone to buy a $750,000 house in the valley and drive 3 SUVs.
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.
there isn't anything magical about the Ramen profitability point... However - you;'ve been gorwing revenue/profits up until that point - customers wont magically stop appearing as you hit it - so you're likely to go past just living on ramen.
More importantly though, you're right - its about extra space and better control not infinite space.
