True. Defense, police and courts all are necessary societal functions. The question is, can these be done better in the open market? Its arguable that rich folks and other elites already don't believe government can handle these functions (ie. they hire private security forces and top legal support to supersede incompetent government services). It does take some shedding of preconceived notions to discover how private entities can better perform most if not all services. Remember, in Soviet Russia, people didn't know who would make cars if the government auto industry shut down!
