With a resistive, electric burner, your point is valid, but we are talking about an inductive range. They don’t work by conducting heat from the range to the pan. They work by inducing an electric current in the pan itself. The heat is produced within the metal of the pan, not within the range. The pan does, indeed, need to be thermally insulated from the range to minimize heat loss.
