And we've done that. The point, as you note, is NOT to prevent infections. The point is to drag out the infections over time so that hospitals aren't overwhelmed. The same number of people are going to get infected. ...just stretched out over time instead of clustered all together. All these PSA's about "Say Home. Stay SAFE!" are horsedip. The PSA should actually be, "Stay Home. Get Infected Later."
The thing is, stats seem to support the suggestion that infections peeked (the top of the curve) in mid-to-late April. Honestly, at this point, the only reason to "self quarantine" if you're healthy is in the hopes that you can delay your exposure until a vaccine is developed or until everyone else has gotten sick and developed herd immunity. So "Stay Home" is all about, "My plan is for EVERYONE ELSE to get sick before me." Which is fine except that it seems like everyone else is being encouraged to make the same plan. It's like the entire world is going "I don't wanna try it first, you try it first... No you. No you. No you."
"Flattening the curve" still means you get sick. But there's been a concentrated global misunderstanding where people seem to think that if they just follow the healthy self quarantining and "social distancing," then they're going to not get sick.
Peace favor your sword,
