you tell me how you are going to test 330 million people in a timely fashion. I’ll wait”
You roll it out city by city, or region by region. As Trump himself has said, we can’t turn everything on all at once. But we got to start the process.
Obviously, the ultimate goal of mass testing is doable - we did mass polio and smallpox vaccination - it’s simply a logistical matter of how it gets done.
So by the time you are done testing one city the results of the other is no longer valid. It would take weeks to test one city of millions of people. And i’m sure the rest of the nation would wait patiently for their turn to come months or years down the line. What you propose is simply not rational or doable
