Funny how most people in this thread consider themselves aggressively independent minded, but when the silicon valley prophet releases his monthly creative writing piece disguised as a scientific discovery they defend and praise it tooth and nail.
To view the majority of human beings as livestock, metaphorically or not, really shows the kind of person he is. Everyone is for the most part unique and will have bouts of aggressive independent mindedness. No one is constantly questioning the system or breaking rules, Paul would like to think that's what he does but in reality he is more of a conformist than he thinks and if he saw himself this way he would probably not use the term 'sheep' to describe it.
We'd all like to think we belong to Paul's upper right quadrant (which, mind you, isn't even very well defined) but in truth you, me, and even Paul himself are more conformist than we think and recognising that is an important step in being intelligent and not shielding yourself from criticism.
For example, I don't think wanting to go and pursue a business idea is independent minded. The overwhelming majority of people would like to do this, even your employees. Actually putting in the effort isn't very independent minded either since it's mostly a matter of how much capital, free time, and social safety nets you have, not how much of a free radical you are.
