People don't weigh the office against nothing. They weigh it against their kitchen table, no train fare and an extra hour in bed. That's the real competition. When someone decides whether to come in, they're running quiet maths on time, cost, travel and everything waiting for them at home.
You won't win that maths by pretending the commute is a treat. It isn't. Nobody enjoys a delayed train or an hour in traffic. But you can change what sits on the other side of the journey, and that's where the decision is actually won or lost.
