If this virus goes unchecked, and we just "open" the economy up again, millions of people will likely die. And what would be the economic (and personal) cost of that? You're making an assumption that, if we just go back to "normal" now, fewer people will be hurt than if businesses stay closed. Look, this isn't hard: just shut everything down completely for 3 weeks. Like, everyone go the fuck home and stay there. Then, in 3 weeks, we can begin a return to normal.
