Every government has a duty to protect the moral and physical health of all its citizens. Firstly, the defining characteristic of sadomasochism is that it does harm to others. The activity has a victim. It is not a simple question of one individual being permitted to harm himself. Secondly, the fact of the victim’s consent is immaterial. The use of seatbelts is mandatory because citizens should not be allowed to risk their bodies for such a nugatory freedom. Citizens are allowed to lose or jeopardize their material assets through foolishness, since the assets are replaceable, or at least not critical to survival. Paternalism exists to protect people from themselves.  As noted below, governments are able to exercise varying degrees of regulation over potentially harmful activities according to the contexts that they occur in. Under these circumstances, the beneficial aspects of contact sports, risky performance arts and non-essential medical procedures can be balanced against the harms they might cause. Dangerous sporting activities invariably occur in public, are supervised by coaches and referees, and are subject to rule-sets agreed on by players and overseen by professional bodies. Under such circumstances, it is possible for the state to be satisfied that risk to the individual has been minimized as far as possible, and that there can be no confusion over which risks an individual consents to.  Where altercations on the sports field result in criminal prosecutions, much discussion is focused on the risks that the victim foresaw he would be exposed to. Hockey players have previously been held to have implicitly accepted the possibility that they might be deliberately struck with a hockey stick in the course of a match [i] . A recent English case ruled that a rugby player does not impliedly consent to run the risk that another player might bite and tear at his ear during a match [ii] .
