I agree with your first statement 100%.
Regarding your second statement, I am assuming you are aiming that at my suggestion of Non-instructor and Instructor level of blackbelt. I was just looking for a way to eliminate all the messy dan ranks and what they imply with teaching authority. Some schools say you have to be X Dan (maybe 3rd or 4th) to run your own school, but can assist at Brown Belt, or 1st - 2nd black, but even as an instructor can only promote up to one, or two levels below you before appealing to a higher authority, etc. This just seems very messy to me. I say, acknowledge skill with a basic Black Belt, non-instructor. When your instructor feels you are capable as an instructor yourself, whenever that may be, then you become ranked as Black Belt, Instructor. Then we put an end to all the special considerations and limitations.
Rank no longer becomes an issue down the road. Is there more to learn? of course. Are there others with more skill and knowledge? of course. Keep up with your own training and learning, but eliminate all this ranking nonsense.
These are just my thoughts. I think we have allowed rank issues to become too complicated. Once upon a time, this was not the case. You were either a student, or you were a teacher. When you were given a teaching license, that was the end of it (but not the end of your own training and growth, of course). I think this simplicity is better and less confusing.
I could see a lot of resistance to this idea from those who claim high rank, and especially those who like to be in control. To adopt a system like this, they would have to give up the "prestige" of their high rank, and would also have to give up much control over their martial arts empires. They no longer get to have much say over the ranking of their student's students, and such, but would rather have to trust that they granted their own students the Instructor ranking for good reason, and this next generation will also exercise good judgement in their own teaching and rankings. I don't expect many people to actually do this. It goes against human nature. It would be a breath of fresh air, however.
personally, if I ever start to teach, this is how I will do it.
