And if it was about the lives of many being saved by sacrificing a few, there might be something to argue, but that is not what this is about. This is the comfort of the many against the lives of the few. And sorry, lives matter more than comfort.
Except the economy isn't only about comfort. It's about people feeding their children, new medicines being developed, people keeping their houses and paying the rent. People die when there is a major recession. Between poverty, crime, addiction and suicides, on top of the sacrifice of the basic freedom our entire society is founded on.
The question isn't "Deaths vs comfort". It's "Amount of deaths that happen quickly due to illness" vs "Amount of deaths that happen over a longer period due to poverty + the sacrifice of everyone's freedom".
It's only reasonable to keep people in lockdown as long as it takes for hospitals not to be overwhelmed.
Yes, I can empathize with the 90 year old who dies of CV-19, just like I can empathize with the guy who overdoses on painkillers 2 years later because he lost his job, his house and his wife. Or the guy who gets stabbed in a mugging 3 years later because his mugger couldn't pay the rent. Or the abuse victims trapped in the house with their abusers.
