You trade off adding limitations for how much you can do in a design and move things around freely, and in return you gain more convenience and less work needed to organize designs. You can change designs around quickly… as long as they’re within the rather confined limitations of Auto Layout.
I think the fundamental disagreement is that one person sees creative empowerment as freedom from doing busywork, whereas another (including the author) sees it as freedom to experiment with a design without limits. Neither is inherently wrong, but the two are inherently in conflict.
