90000 people die in Sweden every year. Shutting down the economy for a 5% increase is not reasonable.

No one shut down economy for exteneded period of time in Norway or Finland, they did just intermittently and now they have exactly same economic situation Sweden. Not worse, not better, but much less death. So 5000 people are dead for nothing. Even more importantly, explicit denying medical care to everyone after, say, 75 y.o. will save lots of money which can be redirected to fun stuff (lowering taxes etc.), and your death rate will barely go up; no one does that though, because that would be considered completely inhumane.
