It is not always to just "ground their power" to neutralize it. Oh were it so. That is far...far.. too simplistic. At a point when they are not using dumb force; things can get dicey and you need to be capable of much more. In a face off with other people with better understanding of power you will be played and manipulated rather than them let you have a stand off of power to power, Hell even a good soft wrestler (yes they exist) will pick that apart. At that time, the ability to make change far surpasses the one point connected model.
sometimes in the near future, would like to meet up with you to learn about your model. i have few points of reference so i am limited in view. would like to know more about the holes/gaps/limits in my model.
