Why do you think spot-testing is misplaced? Are you advocating no testing at all and just letting the virus run it's natural course? A form of viral eugenics?
Agreed that most COVID-19 cases are mild. IIRC, about 80% are mild, about 20% severe and 1% fatal. Of course, 1% in a population of 327M is 3.27M. A significant number I certain we can hit given the nation takes your and Teflon Don's advice to ignore medical advice and just let this virus run it's course.
TBH, while I have vulnerable family members, I've faced death so many times that I just follow the Serenity Prayer and not worry about what happens. Que sera, sera, ya' know.
God, grant me the serenity
to accept the things I cannot change,
the courage to change the things I can,
and the wisdom to know the difference.
Living one day at a time,
enjoying one moment at a time;
accepting hardship as a pathway to peace
