You are looking at it the wrong way. Driving something so large that it would require a commercial license to transport your family around is ridiculous
They don't require commercial licenses though, because they're not large enough to and don't serve a commercial purpose when transporting families / their things. Plenty of families have the need for third-row seating and the ability to haul things around.
