Noone ever goes to a server alone and waits for someone to show up, especially not in OJP. In theory I would agree with you but I think we've had more than enough practice by now to know that this isn't the case, sadly.
People tell their friends that they need someone to play with via IM and then join the server. If noone is on, they ain't connecting either. If what you were saying was true, every server would have to have one person on it at least, right now.
