Many arguments for handling bad things often do not take into account the unintended consequences of that specific handling. This is one of them.
The lockdowns for Coronavirus is another. I don't know which way it actual falls (lockdowns still extended life expectancy or the reduced life expectancy) but I will be curious in a couple of years what the data will show us.
Some people are absolutely certain X will be the best way and either don't take into account the downsides or hand-wave away the concerns. I wish we could have actual debates to come to a solution instead of making it person or political ("YOU WANT TO KILL PEOPLE" vs "YOU DON'T CARE ABOUT PEOPLE"). But tis life I s'pose.
