You make great points, and basically make my argument for me.

One thing I'd add is there are some of us (me included) who resist the social angle of work. It's how I'm wired, and it's taken me a long time to acknowledge and support the efforts to make teams cohesive.

Building great teams is probably the hardest thing in business - the technical stuff can be figured out. And I say this as someone who'd rather work with the technical stuff, and I schedule meetings in my calendar, and reserve small meeting rooms, just to have quiet time to get work done.

It's incredibly difficult to foster great teams, build connectivity between people, when you're not in-person. Being in-person is also where those spontaneous conversations happen that do things like bring people together, or come up with solutions to troublesome issues.

Motivating someone like me to actually be in the office is sometimes necessary.

You nailed it that finding the balance point is the answer. I've been fortunate to work in businesses that understood this, and trusted everyone to do what was needed.
