Hi John, I appreciate you sharing your thoughts. It sounds like you, and most people, want more freedom yet are figuring out how to best achieve it. Self ownership is simply the recognition that you own yourself and your body, as it is your brain that ultimately controls your body and movements. The NAP is an ethical principle that follows from the understanding that each human owns themselves. Libertarians advocate for the adoption and application of the NAP to all human interactions, with the goal of encouraging peace and reducing violent conflict among humans. Pulling a man back to keep him slipping is trying to defend him from impending potential death and harm - not a violation of his persons or his will. Also the NAP is an ethical principle for humans because it isn't necessary for humans to harm each other for survival. Humans make their food from organic sources, such as plants or animals, to survive which is why the NAP is only applied to humans.
