The question is what actionable information would come of expanded testing? We have irrefutable data on hospitalizations and outcomes. We test suspected cases because the results determine the need for hospitalization. We test before discharge to be certain they are clear of the virus. My thinking is that hospitalization data is a valid sample of the entire population. We only need to observe hospitalizations to see how the pandemic is playing out and make decisions on reopening the economy.
If asymptomatic persons infect others, then some percentage will have symptoms, present themselves to a hospital and be tested. The only action on positive results on asymptomatic people is to quarantine them. That result does not add to our knowledge relevant to making protective measure decisions.

How so? If we can determine that there is a predictable percentage of asymptomatic people walking around we can predict the spread and infection rate with much greater certainty. We can also determine high risk individuals might need to further self isolate.
