Oh gosh - I 'm not sure I have the energy or the crayons to respond to this, but here we go.
Contracting COVID is not "essential 0" for vaccinated people. mRNA vaccines provides a 95% risk reduction, less with J&J, and less against any of these variants. None of these are = 0. This has been widely published.
About 38,000 died in car accidents last, about 500,000 died of Covid-19. 38k is not less than 500k. Not that these two are events are even comparable equivalents. See "false equivalents".
Just because you can't mitigate all risk doesn't mean you can't practice risk reduction (or a modicum of common sense). First remove the threat then remove the protection.
Not sure what you were a [preppy] student of, but I'm guessing it wasn't math, science, or stats. TV/VCR repair, maybe? 😉
