Three variables that determine a start-up's success are its 1)product 2)market and 3)the team. Of these, the team is the most important. With a talented team, you can build, get feedback, and reiterate faster on your product. A team that can reiterate every week has a competitive advantage over the team can only reiterate every month because it can push a product out 52 times/year as opposed to only 12 times/year. A team with multiple A-players is always better than a team with just 1 A-player, and their products will be too.
Blame is easy to pass like that, but it seems to me like this startup is bound to die because of a lack of action, more than anything else.
And regarding your opinion, there have been many individuals able to move mountains by themselves when starting out. And there have been many teams of A-players that failed because of irreconcilable differences between them (i.e. too much testosterone, lack of leadership, lack of vision, etc...) - a book I loved reading on this subject is "Dreaming in Code": http://www.dreamingincode.com/
