Isn't that kind of how society works? i.e. If a senior employee benefitted from having close mentorship and a strong social network when they were a junior, then they may wish to pay it forward by being present and mentoring juniors now that they're a senior.
Wishing to go to office and make friends is very different from forcing everyone to do so. Many of us remote senior workers have rich social lives and were able to upskill ourselves, without needing coworkers to substitute for a failing social experience.
