I get how soap works by breaking down outer layers of cells, especially in viruses and bacteria, which is how it protects us (correct me if I’m wrong). My question is why does everyone, including surgeons scrubbing in for surgery, massage the soap around their hands and arms? Couldn’t we just apply the soap, wait 20 seconds, then rinse it off? Maybe it’s a surface area thing, making sure soap is applied everywhere?

You lather the soap and scrub/lightly abrade the skin. The lather is what encapsulates the dirts/oils/grime and leads to cleanliness once it is then washed away. A soap that does not lather is not nearly as effective as one that does.
