Is their health care capacity at risk? If not, then so what. There is no containing or stopping this bug. It will run its course, either quickly or slowly. “Flattening the curve” is supposed to ensure the emergency medical system isn’t suddenly overrun. It’s not going to ultimately stop the spread of the bug. If they could do that, we’d never catch a cold.
Anything beyond flattening the curve enough to ensure continued available emergency care is just delaying the inevitable at the cost of destroying the economy. And you have to have an economy to have a health care system in the first place.
A valid point that is seemly lost in the discussion; it has never been about avoiding the virus altogether, only buying time to prepare the healthcare system and finding possible treatments.
