Sure, if you mean that the capacity isn't there.
And sure, if you mean it won't be 15% of the total, but rather 15% of the 70% of the population who catch it, then ok.
If you mean that that level of care isn't required for the 15% of severe cases which was seen in the studies, then you'll have to refute the studies of people who know more about this than you, with some better arguments than that.

Sorry, but where in gods name is this number coming from? There are currently a few hundred cases documented in Italy,rate of new coronavirus cases worldwide has slowed down to about 500-1000 per day.
For reference, the US has about 1 million hospital visits for pneumonia every year. I couldn't find numbers for Italy but I assume it's in the ballpark of 200k relatively speaking. So a few hundred extra cases or even a few thousand aren't going to push the system anywhere.
Not really.
