One cannot really keep an economy shut down for long, certainly not 18 months like the White House was throwing out there. You wouldn't have an economy (or country) to return to - literally there would be no production left, no economic worth left - no one but a very sliver of society would have the purchasing power to buy anything (and even fewer still would have survived up to this point). Sure, you might wait out COVID19, but the starvation, rampant crime, disorder and sociopolitical chaos would likely consume the nation - killing tens of thousands of people. Without jobs, people have no purchasing power, without purchasing power, they can't acquire necessities without stealing it from others, those who won't or can't out-muscle the haves will die. Handing money to the businesses doesn't really solve the problem - they will just store it and wait. Without consumers, most companies won't survive - they'll die out. All that production going idle will mean supplies will dry up. It would make Detroit look like a summer vacation on Fantasy Island comparatively. Think Somalia or the world of Mad Max - except without all the hope.
