Might it not be more efficient to suspend all global economies simultaneously? Only keep food, energy, hospital, communications, etc. functioning. Everything else stops. No rent payment, no rent collection, stop all money into and out of banks. Food etc. then delivered to fully locked-down homes. Essential workers work for free in return for, say, zero income tax in the future.
It might be easier to restart the economy as and when. (At the moment we will find society divided into two groups, those who survive financially and those who don't.) Also the world we come back to would be quite nice, one where essential workers are on zero tax. Obviously not lawyers, then! Or even mathematical modellers in my view!
