But then what? Let's say we grind everything to a halt and stop it at the price of people starving in the streets and national debt that crushes our dollar to levels we've never dreamed of. Well, as long as there is one case in the Philippines or Russia or Turkey, we'll have to shut down international travel indefinitely or else it will immediately ramp back up once one asymptomatic person slips through into a crowded airport.
I guess we might develop a vaccine in a few years. But we might not. And even if it's twice as effective as the flu vaccines, we'll still have millions of cases a year.
So are you proposing we grind the world to a halt until we find a vaccine that may never come? What's the end game?
