Coordination starts getting hard when you have more than three people in a household. Up until that point, it’s relatively plain sailing unless you have wildly different expectations.
This can be extended up to 12 or so with simple aids like a chore wheel, and a community norm of “it’s okay to ask anyone to do a chore with you especially if it’s their turn.”
I’m not just talking about household chores with this point. Everything gets harder past the 2-3 person mark. That’s not to say higher numbers are infeasible or undesirable, but that it becomes a qualitatively different scenario with its own set of problems.
