It may be worth remembering that social distancing isn't binary. Everyone can go out and find examples of people doing things which they judge to be wrong. The important question is one of scale. Is this everyone? Most people? A small minority? Anecdotes won't answer these questions and it is at scale that the impacts are measurable. So while one person may be virus positive and outside, the opportunities for their interactions may have diminished through structural changes (things being closed) and social changes (hygiene, less risky forms of interaction, a portion of the population isolating).
