If fiction is what we are, then fiction is what we will become. All you attempts and thoughts will be undone. It is in our nature to nurture these thoughts, for without them we are mere vessels unsought. So to claim an avoidance of self to create another fiction, is simply feeding the snake another mens to extinction.
But I do get where you are going with it.
Nature is real, body is real, we use fiction to give purpose, cause, and direction, to these two. Our ego is a caricature of ourselves. Society is a fictional construct that works and has power because we collectively believe it. We use myth and fiction to understand reality and build new tools to knowing ourselves.
Money is one of the greatest stories ever told because it is a story the everyone believes..
