I would say that in the list 'Protection of the integrity of the individual citizen' is something that a NHS would serve. Individually, people want to know that if they get injured or sick they can be taken care when they can't for themselves. Everyone is at risk of these things. Society as an organism also benefits from having resources dedicated to repair of its components in the same as it does in defense of external threats. 'Protection of the territory of the state' also can be served by an NHS because of the damage and danger of highly infectious diseases.
