Your theory seems to rely on a rather uncharitable set of assumptions.
I wonder if an alternate explanation could be that the manager job role tends to involve a lot of talking to other people, and that there's something advantageous, or at least more fun, about doing that in person?
Or perhaps the type of people that become managers tend to lean more toward extroversion, and thus on average managers enjoy in-person social interaction more?
I often meet and talk with people for 6 hours in a day. Have you ever talked on video calls for 6 hours in a day? Every person has a slightly different quality of microphone setup, you can't make eye contact, it's harder to read social cues, you can't get fresh air by doing a walking 1:1, etc. It kind of sucks, like, a lot. Especially for people, like myself, who ended up managing because they simply enjoy being around other people. It's just not that fun to talk to a plastic rectangle all day.
Now, I do still sneak in some IC work from time to time, and it's obviously great to do that remotely. And I understand that most of my reports spend most of their time doing that kind of work. So I wouldn't push them to go back into the office; remote work is the right thing for the team overall.
But if you surveyed me, asking whether I'd like to return to the office? Fuck yeah, I'd like to. But my motivation has nothing to do with your ungracious views on managers needing to feel like bigshots. I'm sorry that you've evidently worked with poor management to the extent that this is your worldview.
