It is also worth noting another unsayable fact at this point: approximately the same number of people have always been projected to contract Covid-19 in most ‘curve flattening’ scenarios. Lockdowns simply spread the deaths out across a longer period of time.
The original argument for locking down to ‘flatten the curve’ was very specifically about stopping patients from entering hospital in a single stream that would overwhelm healthcare resources and cause millions of incidental deaths. Now, however, we know that hospitals have not been swamped on a large scale in any of the non-lockdown US states, nor in nations such as Sweden which never locked down. In fact, more than 200 hospitals in lightly hit areas of both lockdown and social-distancing states have begun to furlough their employees, after cancelling elective procedures in preparation for a Covid wave that simply never arrived.
