Excellent point.
However, neuro professionals seem to prefer more complex explanations, and avoid using the term unconscious.
To me the theory that seems most consistent with research and my personal experience is that we have multiple selves (self modes/ego states/roles etc.), and only one of them is active at any time. Single continuous consciousness or self is an illusion of the mind.
Each self has it’s own will. For example one self can decide to wake up early. If another self is active when we wake up, it can decide to do something else. Being consistent is not so much about will power, but about which self is active.
You can start to control your behavior better by first observing which self is active at any time, and later trying to control that, and not being identified by harmful selves, in other words by increasing your meta-cognitive capabilities.
You could say that your consciousness (or level of consciousness) increases when you are conscious about your consciousness. This is really very difficult, and in the beginning you can do only for short moments before you forget to be second-degree conscious again.
Few examples where “unconscious” beats “conscious” hands down are dancing and driving a car.
