With that said everyone will "most likely" spend a great deal of their training years giving and receiving painful techniques. Like I said above, the pain is most likely the birthing pangs of great technique. The hope is to one day have such great technique you won't have to have the crutch of pain compliance.
I don't really think so, to be honest - I think it's the wrong path to take from the beginning. Seriously, not to be confrontive, but why practice Aikido that way if the goal (and "great technique") is to eliminate the pain, why not learn how to do that, properly, from the beginning? (Although I admit, you're right, most Aikido is indeed practiced that way....)
