Your mothers' hospital should be running tests with that other 50% of unused utility right now. Conduct trials on patients found to be positive, etc. That's literally the second point Gates made.
> It's not practical any more to try to contain the outbreak. The idea at this point is to limit the number of cases at any given time to prevent overburdening the local community's medical resources.

The only thing your intuition and experts agree on is the knock that the world economy is going to take. I challenge you to provide models that show that your "practical" handling of this situation won't have the same disastrous effects on the economy when instead of 3% of a smaller number of the population die, 10% of a much larger portion of the population die. These numbers are in line with countries that implemented lockdown early or have very strong government influence versus countries that implemented lockdown too late.
