This pandemic is the best test we will have had in our history to see/prove if social distancing, masks, and lockdowns actually do anything. CDC has said, even in regards to the flu, they really don't have any idea what works and to what extent. I think the reality really needs to set in for people that no we're not sitting at home until cases are zero. No we are not sitting at home until it's "safe". That is not happening. And for people wanting to hold out for a vaccine, that unreality also needs to set in. A huge portion of people are going to be exposed to this and it is unavoidable. Staying locked down beyond the time we need to "flatten the curve" and bolster the healthcare system to a place it needs to be will start to do more harm than good and basically is delaying the inevitable. A measured and best medically prepared approach to herd immunity with a balanced take towards economic and societal impact is the best option we have.
Also remember, no one can infect you without your "consent". Stop saying all these people outside are going to kill you. They aren't. It's illogical. If you are quarantined you shouldn't give two shits about what anyone else is doing. In fact encourage them. They can all get it and then herd immunity dictates you can come out of your lairs and be fine.
