The idea is to do it well to minimize the chances of this thing getting out of control again, to minimize death and suffering, and to minimize eventual economic impact.
Just like if the US had done the early containment well, the problem would've been smaller and the economic impact would've been smaller. Now that ship has sailed, but it looks like the next phases aren't being handled much better than the early ones, with the daughter and son-in-law and some ex-TV hosts in charge.
