Regarding individuals looking after their own wellbeing... It's very hard for a healthy person to make choices that will significantly increase the chances they stay healthy, short of a massive cost. It's much easier for a sick person to make choices that will reduce the number of people they infect. And it is easier still for society to adjust certain expectations and incentives to help sick people take those actions. For example by not requiring them to go to work(!), especially via public transportation (!!), and ensuring that this is not overly economically burdensome for them. An "individuals should look after their own wellbeing" attitude is a "healthy people are responsible for staying healthy" attitude. It suggests not creating any incentive for people who do fall ill to do anything to prevent the spread -- too late for me, I'm already sick, not much more I can do to look after my own wellbeing than taking the rush hour subway to the emergency room, I guess, and then go straight to work so that I can afford the treatment. When the mathematics work out such that preventative measures taken by sick people are 100x more impactful than preventative measures taken by healthy people for a given expense, why wouldn't we try to encourage those measures to reduce transmission?
