I don't completely agree but your point is well-argued.

I'm bootstrapping my startup in NYC. I've spent over a year focused on iterating from intimate feedback of a slowly growing test group. The core product feels ready for a larger public push, but since it's a social network of sorts, I'm planning to play the long game with it. I'll organically grow the userbase on nights and weekends while returning to a day job. This strategy won't work with all kinds of startups, and once I start this I may find that my assumptions are way off and it won't work for my startup either.

Then, I'll adapt (seek angel funding?).
