This is clearly written by someone who has not interacted much with real-world entrepreneurs. "Agreeable" is not the first word that comes to mind when I think of the entrepreneurs I've met. I'm not saying all entrepreneurs are cantankerous, but I would say they're more inclined to do things "their way."
I also think entrepreneurs are a lot more threatening to the status quo than previous youth-culture archetypes. If you are a recording executive who would you fear most: 1) a drugged out punk rocker who is pissed at the world and letting everyone know it 2) a hacker entrepreneur like Sean Parker.
I think history shows us who the establishment should be more fearful of.
