We don't have to, we just need to keep the numbers low enough that hospitals function properly
According to some comments here, we have a purely free market and all actors are benevolent, there are no profit incentives "for the worse" (at all, that is, let me quote: "conspiratorial thinking" to think that people are motivated by profits) and so forth, but only as so far as we are talking about COVID-19.
I typically read the exact opposites when there are discussions about Facebook, Google, or the market in general.
