This is nonsense. If I, and others I know could get a serum antibody test, those of us that tested positive would go back to life as normal - including work and opening businesses back up.
It doesn’t even rise to the level of nonsense.
This author couldn’t even knock over his own strawman.
Why The Federalist would publish it is a mystery.
If you tested positive you would act like as if nothing was wrong? Sorry but that doesn’t make any sense to me. Maybe I misunderstand you.
