This is only tangentially related to "Why Silicon Valley Works", but am I the only person who is frustrated by "famous" VC's saying that "founders should stop worrying about their valuation"?

I can't get over this. This is like a used car salesman telling you not to worry about the cost of the car, just to remember that there are free weather mats included!

I feel that there is a connection here as to "why Silicon Valley" works from the perspective of VC's in a position to influence founders. However I'm not feeling particularly eloquent today and haven't fully formed these ideas.
