It's likely that every one of us will probably get the virus in the next couple of years, it is novel, nobody has an immunity. Banning large gatherings is to try and make it so that we don't all get the virus in the same month; which would overwhelm local hospitals.
We have 2 hospital beds per 1000 people in California; 1 percent of Coronavirus victims require hospitalization.
If 50% of people get sick, that's 500 people from the thousand
1% of that is 5 people.
2 people get beds, so 3 out of 5 people those people... die I suppose.
Lets not forget that those hospital beds can't be used to treat other urgent care items.

Our capacity to treat the symptoms of the disease is limited. Current efforts on social distancing are based on slowing down the disease spread so that our health system has a chance to keep up.
