He can’t mean that we don’t visit the kosel, since we do, and that is in fact part of his moshol.
He can’t mean that we let the Waqf destroy archeological evidence, since his moshol is that we are too busy with the box. Besides, what mitzva is there to have archeological evidence?
He must mean that we don’t throw rocks from har habayis at people davening.
