Most people who compare Italy (and soon the UK) to say, South Korea or Taiwan would probably disagree with you. Also, whilst you might not mind a few hundred thousand or million dead pensioners, I assume at least some of them would rather spend time with their grandchildren than slowly suffocate amidst the remains of a collapsed health care system. Shouldn't the whole overwhelming uncertainty thing predispose you to not trying to infect a few billion people and see what happens? Did it ever occur to you that herd immunity via mass infection might either not work or could cause a lot of long term health problems in people who are not pensioners? If not, what makes you so sure?
