I have no doubt that you believe this. The problem I am presenting, though, is that in order to proceed with this theory, one has to overlook the most direct experience of consciousness. It is as if your friend Mike is in the room and you and a few other friends are sitting their discussing with each other what you think Mike would like to eat for lunch. All the while, Mike is sitting there saying, "hey guys. I'd like pizza. Let's get some pizza," yet you and your other friends continue to speculate on what Mike wants. So you start considering what he ate earlier in the week, what he doesn't like, what he's allergic to, etc. So you go on in this way while Mike is there trying to tell you directly.
Similarly, if you want to understand self, then you will take directly the consciousness. Trying to understand it by considering external factors is a waste of time.
