It's not even about just saving lives if the thing I saw recently about the effects of COVID-19 on survivors is accurate - diminished lung capacity, impaired liver function, possible cardiac issues, possible neurological issues, blood clots that may lead to strokes later, etc.
Currently 750k survivors - health systems could possibly be looking at a generation or more of strain coping with them.
Or we can flatten the curve and reduce the number of infections and thence the number of infected survivors.
Flattening the curve is only about spreading the same number of infections over time, so that at a given time, the health system is not overwhelmed. It will not reduce the number of infections, and will likely augment the number of survivors, who might have to deal with hard long term consequences.

It got into ridiculous situations where a friend who is an urology doctor was on paid leave for last few weeks, simply no work for them under these rules. Another friend, radiologist in a hospital heavily hit by covid, worked only 4 hours/day shifts, instead of usual 10-12 ones.
So no, hospitals definitely don't treat everybody they used to, only those that would literally die if postponed. And even there sometimes they don't, ie they stopped resuscitating severe heart attacks here few weeks ago, because its too equipment-intense and uncertain. Equipment is +-same as that used for covid patients.
Most of the normal workload for hospital isn't emergency, but all those non-severe treatments like dermatology, arthritis, broken bones etc. That's maybe 80% of the staff.
I'm assuming specialists ain't allowed to work as generalists, then? I'd imagine that specialized doctors (like urologists) should be able to double as PCPs should the need arise (like, you know, a global pandemic). I ain't a doctor, though, so I'm perfectly willing to accept "specialist and generalist practice are too different from one another" as the answer here.
The lives being saved by flattening are not limited to covid-19 patients requiring intubation.
It's also about saving the lives of people who aren't covid-19 infected at all, but require emergency hospital care, which there's a constant supply of on any given day in a major city.
Frankly I'm surprised we're even having to clarify this at this late stage, sigh.
