This is turning into more of a philosophy/religion topic as appose to the survival principal of the function of EGO, in a social dynamic. If we were just forces that were produced solely in our mind then perhaps the function of the ego would not have to intervene in day to day practices in this reality we function in. For some if their was no ego, I do not believe they would take breathes. My opinion is this, a strong balanced ego is important to survive. It helps you strive to be better, Lets not forget WINNING, anyone know how it feel to win? Ego is pretty important, again I would emphasize if we did not have a ego, we would be like a insect bee society.. Not my cup of tee... Under some kind of control.. No thank you..
