People dying isn't the only consideration; public policy isn't made with the assumption "save human life at all costs", otherwise e.g. private cars (which kill 1-2 million people per year and injure tens of millions more) would be banned by now.

If healthcare capacity in the US becomes overwhelmed by an exponential function, every moment wasted by officials now, while the numbers are still low enough to do something real about, will turn out to have been a moment responsible for many thousands of needless deaths.

I hope your flippancy turns out to be warranted. I just can’t get there.
