To be honest, I imagine they'd all still exist even if YC gave no funding. A program like YCVC would exist (because VCs put inordinate trust in YC) and startups would get the funding they need.

And, let's be honest, $120k really isn't a lot of money. Sure, it might be more than my net worth right now—but as an engineer I could easily save up that amount in less than 2 years.
