If I had a student with a similar problem I'd tell him I thought using towers was a bad idea but if he insisted on it, then I'd let him use towers, get lost, get scared, and then tell him where he was. That way he understands why not to do it. That may not be the right answer but I've had a cocky student or two who just won't believe you know better..till he trys it and can't make his plan work.
