 According to this rationale, the task of public health ethics is not necessarily to justify each particular decision or intervention directly. Rather, as long as it stays within certain pre-established parameters, public health public health in general can be justified in the same way a market economy, the laws of private property, or other similarly broad and useful institutions that involve some interference with free and equal persons but also enable individuals to access greater benefits can be justified: when properly regulated and managed, their existence is by and large better than their absence for everyone. So structured, the justification for particular public health interventions, requirements, or restrictions is derivative of or parasitic on a higher-level rationale.
