The point is not that punctuality is a virtue, but that a professional is capable of adhering to certain agreed disciplines, regardless of how important, or virtuous they may or may not be. A professional does not make the mistake of judging these activities for their intrinsic value, but sees them as an opportunity to develop discipline, which is useful and valuable for more important activities. For examples see: the military, professional orchestras, rowing eights, ivy league traditions, and even children keeping piggy banks.
