The additional important point, of course, is that there are many more 'Why' questions to be asked (often more interesting, and more important than corner cases like human-scale magnetism) that do not get asked just because of familiarity. Familiarity however is not understanding, and it is the same as simplicity.
He does repeatedly. And continues to explain why there is no satisfying answer, because we normally stop asking "why" once we reach a level of familiarity. That level of familiarity to the layperson is different between electromagnetism and slippery ice.
