I'll try to make it clearer. He is making two distinct points, not the single point you think. First point: that it requires special pleading for us to hold that one of the collection of universes in the hierarchy is un-simulated (i.e. physically real). This is the point that all of us disagree with him on. Second point (that is a corollary of accepting the first point): an infinite regress of simulated universes makes no sense. We (including you) all agree with him on this second point. In the above quotes of yours, you are trying to use the second point to dismiss his argument. This makes no sense, as he agrees with you on the second point.
