All of these OT examples of Law, and our breaking them are only there to show us we are born with a sin nature, that we are corrupt from the womb, and incapable of being righteous and holy to the meeting of God's standard.
They're not written in order that we can pick and choose, and decide which ones being broken are "to us" sin, or, to choose which ones we think we have and have not broken, nor to come up with some "theory of sin."
Rather, it is written that we may have a true concept of ourselves, that is, that we are lost and in need of God, totally incapable of coming to Him, while totally dependent upon Him to save. Thus, man has missed the mark, is sinful, bound for destruction, his very nature being sinful and corrupt, which is not dependent nor activated upon mans personal decision to commit an act of sin, for he is already lost within this state at birth. Man sins because he is in a sinful state to begin with. The words and indictment in Romans 3:23 "for all have sinned and fall short of the glory of God," carries much weight when understood within this truth.
