It's a lot more than just 'looking silly'. The lockdown kills many jobs leading to people losing hope and triggering a recession worse than 2007's. That will have its death toll too.
It's not clear to me the economic result would be much different.
I'm tired of the cure cannot be worse than the disease rhetoric. Economies will recover. The dead won't.
And really, if we would do everything possible to prevent deaths, we would have tackled traffic, alcohol, poverty, pollution etc. In some countries even poor healthcare overall (Trump is still fighting 'Obamacare').
It's not as black and white as this; the virus isn't the only problem in our society.
