Up to a certain point I agree, but I do wonder about the problem that startups can appear out of nowhere if they think there is investment money to be had just for showing up. In other words, your very willingness to fund many startups, may cause the quality of startups to decline. The analogy to stock picking is not complete here because you buying stocks in many different companies (an index fund) doesn't cause more companies to go public. But, if it doesn't take much more than a slide deck and a good talker to take your money, you will easily have 1,000 startups show up that each have 0% chance of succeeding.

Not saying this is currently a problem, just that it could be if most VC's tried to take a "place chips on all the numbers" kind of strategy.
