Since our testing capabilities are severely lacking, it makes sense to limit what we do have for the cases that need to be confirmed for treatment.
Everyone else needs to take responsibility and social distance properly. However, I'm not really seeing our leaders tell people how to do that, nor do I have a lot of faith that many of our fellow citizens understand that avoiding crowded restaurants, grocery stores, etc is the point. Lots of people seem to think it's an extended Labor Day weekend cookout
Once we have more tests, obviously, we need to test aggressively
You're missing the reasoning, but you're in good company because the media and many others have been wrong on this for a while now.
We are now getting to the point that we now have much more testing capability and in many locations more tests than people we are willing to test.
The tests aren't the scarcest of our finite resources anymore.
The healthcare workers who are needed to administer the tests throughout the whole process are needed for higher priority tasks, and we also need to minimize their exposure to infected.
The physical resources in terms of space are also limited, and testing is likely to bring infected into contact with uninflected who wouldn't be in contact if they all stayed home.
More importantly, we have a PPE shortage that is a much bigger concern right now, and precious PPE is getting used to test whether or not someone who probably doesn't have it actually has it. Even with the restrictions we've placed on testing, most people are still testing negative in the US.
Many of the tests give false results, so you aren't Even getting the certainty that you want.
People don't need to be tested. People need to treat themselves as infected if they have any reason to believe they're infected.
And those who don't have any reason to believe there infected need to understand they can be asymptomatic and practice social distancing and proper hygiene.
The lack of Testing is not the problem right now. Testing for an insufficient reason is a much bigger problem.
