Not using the UM service doesn't change the fact he is still 15 and an unaccompanied minor - he still can't do any of the things listed, you can just choose not to take the full service. That's my read of it.

Kind of like someone who needs mobility assistance. They can't sit in an exit row, for example but they can choose or not choose the wheelchair service. Even if they don't choose wheelchair service as they can maneuver on their own, they are still bound by the exit row rules. Not using an assistance service doesn't exempt you from the other rules. That's how I am reading it.
