More likely than not the outcome would have been the same even if they were unvaccinated, because covid-19 just isn't that bad of a virus. If you're under 30 years old, even with Wuhan/Alpha/Delta variants, you were at lower risk than with the yearly flu.

This is objectively false; the IFR of all Covid variants is one order of magnitude greater than the flu, with the possible exception of a few years in the century with particularly virulent seasonal flus.
