I disagree, and strongly.
This would be a knee-jerk, hyberbolic, and woefully ineffective over-response.
Typical for the times.
The only thing this might achieve is creating an even greater climate of fear and loathing.
There will be false positives. And false negatives.
There are with every medical test.
Back-of-the-envelope calculation: Assuming we "test everybody", and assuming both a 5% rate for both false positives and false negatives -- which is better than we currently do with influenza testing![1] -- we would needlessly quarantine 12.5 million people, and fail to quarantine an equal number of infected carriers.
Not to mention, the data about COVID-19 is all over the map. We still know very, very little about this disease. Understanding it well enough to calculate the appropriate response will take time.
Testing is part of the solution, yes. But the economic and social impact of "test everybody, every day" would be catastrophic.
Until then, in the short term, there are things we can, and should, be doing, as individuals:
(1) Limit your physical contact with others.
(1a) Especially at-risk individuals. The elderly, young children, etc.
(2) Support your local businesses through delivery, online ordering, and gift certificates.
(3) DON'T HOARD SUPPLIES! You do not need a decade's worth of toilet paper. Three months' worth is fine.
(4) Related to the above, maybe use this as an opportunity to live a bit more sustainably.
I'm down to four sheets per wipe -- certainly fascinating, relevant, and not at all disgusting to all of our readers -- which means that a single CostCo-sized pack of TP might keep my household going for well over six months.
On that note, I'm learning to garden. Let's see if I can manage to actually grow a fucking potato this year, all I got last year was a big leafy plant with zero tubers.
A discussion on government policy in response to this is a big ball of... things that require four sheets of Kirkland Signature, so I'm so not going there.
