It's a bullshit quarantine, which is bound to be the case when they quarantine healthy people, leaving the sick to spread their disease around. It's tyranny, and it's best answered by non-compliance as time wears on. That's why I say we'll do it, but only for a limited time.
The problem with your theory is that there is no way to know on the surface who is healthy and who is not.
At the risk of being repetitive (which I am, quite deliberately) this is not like anything we’ve ever seen before. One cannot make comparisons with anything in the past other than 1918, and even that was the flu.
This is not.
In addition, the point of staying home is to lengthen the prep time for hospitals and keep our medical first responders safer.
The more people who abide by the safety standards, the slower the spread of this disease will be.
It’s not really rocket science.
It’s just science.
