Rowling speaks to an adult generation that hasn't known and doesn't care about mystery. They are inhabitants of urban jungles, not of the real wild. They don't have the skills to tell ersatz magic from the real thing, for as children they daily invested the ersatz with what imagination they had.

The Great Beast is the only object of idolatry , the only ersatz of God , the only imitation of something which is infinitely far from me and which is I myself.Simone Weil
