> I am treating other people as professionals and letting them structure their work the way they think is best
Again, you're ignoring that the office workers preference isn't simply to work in an office. It's often to work in an office (only or primarily) with other people also in that office.
> I am questioning why the office workers try to make other people return to office with bad faith arguments (water cooler talk and synergies), when remote workers seem just happy to be working from home, without pressuring office workers to come and join them.
You're making the bad-faith argument that a person in the office and a person working at home is a win-win situation. The remote workers may be just as happy, but those in the office are not just as happy.
I get it. People like remote work. People want to protect their right to work remotely. But at least acknowledge that some people are negatively affected by the push for remote work.
The situation doesn't need to be a win-win! Somebody can lose out on what they think is best for them. That's 100% fine. It's up to the company to make a decision and then up to the employees to decide how they'll react to that decision.
