2. It's too late

Realistically, we are probably past the never point. The long contagious incubation period and high R0 mean there are probably four or five times as many people who are already sick but don't know it as there are who have become symptomatic. Because they don't know they are sick we don't know who they are or who else they are infecting as I write this. Even if the most aggressive imaginable measures are taken to basically isolate everyone from everyone else, it is probably too late.
