I think you massively overestimate how many people actually care.
My guess is that 95% or more of all Discord users do not care and simply upload their selfie or ID card and be done with it. I know I will (although they did say that they expect 80%+ to not require verification since they can somehow infer their age from other parameters)
Those 5% are the unusual sorts that separate Discord from Facebook.
> I know I will
Are you a minority, LGBTQ+, etc or of a "different" political persuasion that might have any reason to be distrustful of the US government? If so, you probably wouldn't just "be done with it".
Remember digg?
I've already cancelled my Nitro account. I'm quite active on a ~5k member programming server and we're giving Zulip another try. I think it's unlikely we'll stay on Discord.
Obviously anecdotal, but eventually this adds up.
