Yes, I dont code, I drive product vision and business, and completely see where you are coming from. However I need crackpot coders on my team. I view them as equals because I know I'd have no product without them however you are 100% correct in your analogy.
This leads to the question of whether entrepreneurs, who have the ingredients you mention, are born, or if an MBA can teach that?
In fact... I would rather invest the $100-$160k+ from an MBA in bootstrapping a good internet idea.
Get that to finding and you'll get a $2-3mm+ valuation, you've created more value than a job will ever create, you are in control etc... But that's just me.
You are right - horses for courses. At the end of the day its about having a balanced team that can execute across product and business. As an individual you can't be all things to all people. As a founder my strength is in product management and driving a vision, although I have a computer science degree, I choose not to code because I prefer to drive product and business and hire people who are way better than me to code.
