As an introvert, as much as I feel weird aroind people, I feel even weirder video chatting with people I've never met in person. In that situation, I have no idea how to read people and the expectations are way harder to try to meet. This makes meetings even worse until I meet them.
While I agree that forced in person work daily is insane, the OP is complaining about meeting people in person once after many years, which feels equally as ridiculous. IMO even for widely dispersed teams, meeting a few times a year seems ideal.
IANAL, and not that it really makes this bullshit any better but...
It's unlikely that agreeing to terms of service that claim you waive rights to any class action lawsuit would actually hold up as legally binding in court. Many of these agreements aren't reply binding are already legally gray... Plus, universally vaguely signing your legal rights away in any contract doesn't hold any water either.
I highly doubt you'd actually lose any rights to a check box that's bound to "you can't ever sue us".
