TBH the thought has crossed my mind many times lately. At this point, I strongly believe we're all going to get Omicron (and the next variant) eventually, and it's just a matter of time. So, more and more I just want to get it over with.

Except for the fact that ICUs would overflow, it would be fantastic to just have a "once and done" event. Let (and encourage) COVID to sweep undeterred, and all the vaccinated adults get sick for a couple of days, some of the children get sick (and many will be asymptomatic), and all the stubbornly-unvaccinated meet whatever fate awaits them, all at the same time rather than spread out over the next five years.

I'm sure the antivax people would prefer this approach, but killing off 5 or 6 million people (based on a 1.4% CFR) in the US is fucking insane.

Not only does the antivaxxers prefer this approach, it's the approach they are already actively taking. In Florida, for example (but pick whatever southern-US state you prefer): people actively refuse the vaccine and violently refuse all other accommodations (no masks, no distancing, no reduced capacity at bars).
