Sorry, I don't have the experience or expertise to disagree with you on these points, although I do question the feasibility of the logistics. If you hold to these ideals then I think you must be an amazing teacher.
I think you are ascribing something to me that isn't true. I spoke only of the responsibilites of an instructor as I see them. I never claimed that I was an instructor myself.
Frankly, this "ideal" is not that difficult. Any compentant, caring individual is quite capable of living up to it, in my experience at least.
