The reason you don't have to be a gradute to teach the PADI system is because the system removes the need for a teacher to use traditional methods of education - like lectures and self-planned curriculums. The program is fully built around prescriptive teaching. It's a simple loop:
1. Self-study (Manual, DVD/VHS Videos, & Interactive Media)
2. Take a quiz with "examiner"
3. Review with "instructor" what you missed and ask questions
4. Practice skills in the pool with "demonstrator"
5. Perform skills in the ocean with "evaluator"
6. Repeat
Bottom line is you never really teach in the traditional sense. Instead you answer questions and discuss problems and solutions, set a mastery level role-model example, evaluate that you made perfect cookie-cutter student divers. Now there is no way to avoid putting in the personal touch. But one-on-one time with the student becomes the focus, you spend your time anticipating needs and problems of the student. Which in fact becomes the focus, and it's something that a PADI instructor can actually be much better at than a teacher who is in any way distracted by making speeches, impressing audiences, and building ego. You must of course be willing to trust the system, and follow the method. It sounds robotic but that would be to completely miss the point. The point is to give the PADI instructor more time. It's all about time - time to focus on the most important element - the student, time to focus on their needs, time to focus on their issues. All done without regurgitating useless facts and figures and information that is of no use to the sport or the skill set of the student, if the've studied it let's get into the water and put it into practice - GO DIVING ALREADY. In my opinion it is a more pure method than any traditional instruction could attain.
