There are literally billions of people on the planet right now incarcerated in their homes.
The economy is a patient whose heart has stopped pumping - we've injected Trillions in liquidity to hold off 'total death' and even that aid will only hold out for several more weeks. The 'system is collapsing' very, very quickly. The numbers are off the charts like anything we've seen before, all the buzzers in the cockpit are going off at once.
'Contact Tracing' more like chemotherapy, until there's a cure or vaccine, the South Korean model is basically the only example we can expect to try to follow.
Edit: I should add, I don't care about 'the economy' as an arbitrary thing, I don't care about investors or 'the stock market'. But 'the economy' is made up of very real things, like your job, whatever you do - and it's all going down like dominos. The headlines talking abut x% reduction in GDP etc, - those are the 'don't panic it will be ok numbers'. When >80% of the population is staying at home, the system as a whole cannot move forward - it's an 'existential decline' just 'some lower amount of GDP'. It's going to be cataclysmic and will be very, very difficult for the community at large, life-threatening in many circumstances.
The population at large I think has a visceral sensitivity to 'pandemic' - we've all seen the film, we know what 'getting Covid' means to us. But the notion of the economy going down like a house of cards is more intangible to most people, so it's less of a populist issue, but it should be.
Korean style contact-tracing looks different in that light.
