You seem to think that for some reason, ICU beds go unused except in a situation like this? ICU capacity is probably built to meet some fraction of demand in normal circumstances. Those beds weren't all unused before this outbreak started. 737 ICU beds available isn't the same as the total number of ICU beds. Normal health problems that need hospital treatment (strokes, heart attacks, car accidents, etc.) are still happening during this outbreak (well, car accidents are probably reduced now with Italy's lockdown protocols).
