That, to me, is the very soul of Anachronism (or preservationism): recognizing the value in something old and carrying it forward into the world for it's own sake. Manners, for example, were invented by the nouveau riche of early capitalism in order to prove that they were just as good as the old aristocracy, not because these people had a deep and overriding concern for others. Hardly a noble origin, but the practice has an inherent value unrelated to the social circumstances that produced it, and so it is continued (albeit far less frequently than we should like!) to the present day.
