> They have almost completely forgotten the velocity achievable when a team works together.

Your comment simply assumes that superior "velocity" to exist. Many of us have not seen it. For myself, and many of my fellow engineers in other companies, I found that I'm much more productive in remote settings. Our team's productivity objectively increased after we went remote. Conversations with colleagues shows this to be somewhat common in many other teams and companies.

Maybe your personal in-office experience has shown this fabled "velocity". For many of us it never existed, and instead we experienced constant low-value interruptions leading to inefficient loss of focus, lots of time spent "at work" but not actually working, instead socializing or wasting time in other ways that feel good.
