Only way to deal with this problem is to reduce world GDP by 90%.
Won't happen.
Prepare for the worst.
Coronavirus might not get it down by 90% but 50% is certainly possible.
My feeling is that people will feel caged and as soon as they think it's safe, they'll start traveling again and there'll be a giant surge of travel for a couple months, and then it'll basically return to the way it was.
