Given the lemming like behavior of pretty much every government, with Austria going into full lockdown, and Germany maybe not far behind, I don’t think you can rule out a March 2020 like plunge.
There has tended to be a domino like effect on covid policy. If all of Europe locks down, and a bunch of large US states do the same it might get ugly. For that matter I don’t think you can rule out violent unrest and who could blame them? It’s been almost 2 years of this.
I’m not predicting anything other than this is going to end in tears …. someday.
