I would prefer not to be tied to a commute distance of an office with a commitment to waste that commute time and energy every week. What works for you personally is very different from a hard requirement for everybody.
To me, meetings day implies a rule that everybody attached to that office is required to be in to have meetings with, but I apologize if I read to much into it.
Is that not implicit? You stated what works best for you, I stated what works best for me.
