Outside of just being harder to communicate virtually, I really need the change of scenery and social interaction that comes with an office. Sure you can get that by joining different social groups outside of work, but that requires lots of intentional effort, and I actually enjoy hanging out at work and going to lunch with my coworkers. And the office has lots of perks like snacks and meals which can't be easily replicated at home (I mean I don't mind cooking, but I get much better lunches at work than the sandwich I would make for myself). I can't think of a working situation much better than going to an office where I have all of the food I need, a properly set up workstation, and coworkers I am able to talk to in person and go to lunch/dinner/social activities with. To me that is far better than sitting in my home alone all day (and I don't even have kids, which would be a whole other set of distractions).
