You don't need an argument for a preference. If you try to coerce other people according to your preference, you need an argument, as you would in any other context. For some reason, the RTO arguments are very bad. Is there some part the proponents can't say out loud?

No. It's possible my stock options would be worth more if the office workers adopted the more efficient form of work from home. Maybe the hybrid meetings would be more enjoyable fully remote. I still wouldn't think about trying to coerce them into that with talk about synergy or the online version of water coolers. That's a bad thing to do. Let them enjoy the office, and others remote.
