There are several assumptions in your comparison that may or may not be true: - the Shanghai lockdown happened in reaction to a number of infections. For these "zero covid" does not apply. How high was that number? - the current variant is much harder to contain than earlier ones. So it might be that you have a lockdown now, then again in two months, again in two months,... until everybody had it (depending on how well the current chinese vac works against the current variant). - An actual lockdown, much more than the tame western versions, has mental and health costs. How high is the damage of n weeks of lockdown compared to 0.3%? For which n? - Financially, what n can you afford? Is that long enough?
