You seem to be positing that because there is no cure at present, hospitalization for supportive care for covid-19 infection is of no value so far as outcome is concerned. That is clearly not the case. Even if the majority of patients with severe covid-19 infection who develop ARDS severe enough to require ventilator support die, if you are one of the minority who survive treatment will have made a big difference to you personally. It is hard to track the hospitalization rate for covid-19 across the country because most states are not reporting it. But on Thursday March 26, Governor Cuomo reported that there were 5327 patients hospitalized in New York State of which 1290 were in the ICU. Over the weekend new reported deaths from that state have dropped off despite the fact that hospitalizations had been increasing sharply in the week prior and NY is now reporting new deaths of under 200/day despite the fact that multiple thousands of new cases have been reported daily since Thursday. I think it is safe to conclude that a majority of those people who were sick enough to require hospitalization for covid-19 infection are not dying.
