This assessment is only prima facie because, like all agreements, certain con¬ditions must be met before we can conclude in fact that autonomy has been respected and mutual benefit achieved. Thus, for example, we would need to establish that the agreement resulted from an informed and voluntary consent, and that there was no fraud, deception, or coercion involved. When these con¬ditions are violated, autonomy is not respected and mutual benefit not attained. Furthermore, even when such conditions are met, other values may override the freedom of individuals to contract for mutually beneficial purposes. Thus, for example, the freedom of drug dealers to pursue mutually agreeable ends is overridden by society's concern to maintain law and order.
