If there is none, that means you have a non-falsifiable belief that either coercive lockdowns or social distancing has worked in the US with respect to Covid-19. There really is no point then discussing it further pretending evidence matters, because it does not in terms of your belief.
Thinking about it from this other angle often clarifies the issue quite quickly.
