It's odd how you keep overlooking the fact that staying within the capacity of the healthcare system saves lives. You should watch Governor Cuomo's morning briefings. He understands this and explains it very well, and is planning re-opening based on that principle. He has an actual long-term plan.
A healthcare system that is at full capacity cannot care for any new patients, no matter what their problem. Car crashes, overdoes, assaults, etc. all get left outside because the system is full. The main point of flattening the curve is to have some capacity left for the rest of the patients. The alternative is to reject all of the COVID-19 patients because it's an inconvenience. Aside from the moral aspects, doctors have taken an oath, the Hippocratic oath, to take care of all patients.
I can't really imagine a society where we're out and about, spreading disease, because we want to go see a movie or workout in the gym.
I understand the economic reasons, working to produce the things we need to live, and things that can be produced at low risk. But trading lives for personal enjoyment is unimaginable.
I guess it boils down the definition of harm and good.
