Because if you compare the number of infected with flu (let's use 25M) since October 1 with the number infected with Covid-19 today ~45K, the ratio is 555:1. Now, let's assume there's been 30,000 flu deaths this season. As of right now, there are about 1K official deaths from Covid-19. If the ratio is 555:1, then you can assume that with the same number of people infected, there would already have been 610,500 dead.

Now, let's look at the hospitalization stats. Average of 300,000 people required hospitalization so far. 25,000,000/300,000 = 833:1. 1 in 833 people infected with the flu required hospitalization.

So far from the Covid-19, we find that 1 in 5 are SERIOUS cases. This means hospitalization is most likely required. That means if as many people contract Covid-19 as the flu, about 5 MILLION people would require hospitalization. There just aren't enough resources and space for that staggering number of people anywhere in the world, much less the US.

If Covid reaches flu level, there would be social, economic, and political chaos.
