If you were an employer, would you want to hire people that are fundamentally opposed to your business? Never!
In fact, I could hear a perfectly reasonable sounding case from the government why no libertarian should ever be hired by the government.
E.g., "He's says he against what we do. How can he ever be an effective employee for us?"
