"(Harmless): The spell is usually beneficial, not harmful, but a targeted creature can attempt a saving throw if it wishes."
So there is a difference between a harmless spell (which doesn't normally require a save but the target can attempt to resist if they choose) and a spell that requires a willing target (which means active consent by the target). One requires active refusal, the other active consent.
So you can cure an unconscious buddy without trouble, but teleporting them is questionable.
