Jonathan Adler at the Volokh Conspiracy blog has a great example of the potential power of non-coercive mechanisms for social change. In this case, pediatricians are firing patients who won’t vaccinate their children. There is no coercion involved. Patients are free to comply with what the doctors want or take their business elsewhere. Doctors are free to associate with whom they want – or not. Unfortunately, people are often forced to associate with others (or to associate with others only under the terms set by the state) against their will – and would it be surprising if the state ultimately required doctors to provide service to non-vaccinators?
