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.

The asymptomatic would have to self isolate and stay away from high risk people. But we would not learn anything that we don't know by looking at hospital data. We can decide on reopening a lockdown based on the number of admissions. If those drop to nothing, that means people aren't getting sick.

That means no one is getting admitted at that point in time or for some length of time certain, not that they aren’t infected or getting sick. We would need to see no admissions for something like a month since people can be asymptomatic and infected and never get admitted, but still spread the disease.
