Your faith in the government acting benevolently is surprising. There is the phrase "never let a good crisis go to waste"
There were 60,000 US fatalities of people younger than 50 (1 Vietnam War's worth of US casualties, or, if you prefer, 15,000 Benghazis).
Yes, for many of the dead, you can retroactively point to "health issues", but those are _extremely_ common, even among people who generally don't consider themselves "chronically ill" at all. And some of the "health issues" might come down to having a bad set of certain genes that up to now have never caused any significant issues.
Finally, there are other Covid consequences than death. I personally know several people (some of them perfectly healthy people in their early 20s) dealing with fatigue/loss of taste for a year (and counting). Personally, I'm fairly confident that the risk of severe outcomes of an acute COVID-19 infection are minuscule for me, thanks to vaccination (So that's a vast improvement over a year ago), but the risks of chronic complications are not as well managed with vaccines, are not particularly closely correlated with severity of the acute infection, and are, as of yet, practically unknown for the omicron variant.
Even at 0.1% over 7b population that's still a couple million body bags so measures even if only partially effective at preventing transmission are still worthwhile
