Okay, but what if you are the most pleasant and caring cab company in the world, and suddenly a giant, well-funded bully comes into the scene and starts competing with you? Do you just fold and go into a different business("refuse to participate in any sort of society with them"?) How do you plan to educate everyone to be cooperative when you need to disengage whenever you meet bullies? You will need a closed-off society that ostracizes its members when they stray from the golden path. At least your solution doesn't require global dominance and authoritarianism to bring everyone in line, which is a big plus.
