So, I think the thing to do is to let workers talk frankly with their immediate supervisor and they're team mates, and then let people decide for themselves where they would work best from. Weirdly, most people don't go to work with the intent to do a bad job and can be trusted to make that choice for themselves.

That being said, there are some legitimate reasons why some people want a return to office that extend beyond the "butts in seats means productivity" and "people will realize I'm not providing value if we work from home" that a lot of people jump to immediately.

Some professions benefit a lot from face to face communication and coordination. The job can be done remotely, but it's a lot more work. Because rather than accidentally coordinating, you have to be deliberate with every interaction. Wfh has led to a lot less idea spread between teams in those areas, and often there's little idea about how to promote "so I was talking with Jan on the other team, and we had this idea..." Outside of making it so people can randomly talk to one another.

Some businesses have significant investments in their office space. If they're not using it the pressure to divest from an unneeded asset is strong. Because everyone has this pressure, they might lose significant money selling at a loss, or as a penalty for breaking the lease.
If they believe that the wfh trend will slow and possibly reverse to some degree, then they don't want to sell when it's cheap and be forced to buy when it's expensive again. This is often coupled with the previous point.

The final reason has to do with attachment and people. When people don't see each other, they're less attached to one another. If your job is just a place you quietly work and get paid, there's less human connection stopping you from jumping ship immediately.
You are also slower to adopt the company culture, which aside from bullshit buzzword stuff actually has value as the set of poorly defined social contracts about how the company interacts with customers, and generally "does stuff". The actual company culture that makes you know that project plans go in spread sheets, the project proposal in a text document, and how people expect the documentation wiki to be formatted. What style of gif to use to get a chuckle and make people remember the important bit.
It also creates some difficulties for new entrants to the workforce. A lot of people with little or no office experience have reported a much harder time getting situated without people nearby to lend a hand. That process is much harder if there aren't people nearby, so some people want to encourage more people to come back to let that work better.

In the end, these aren't enough for me to think we should be forcing people back, but they're worth considering and talking about as a company or team.
