You have a point about the increased fold equity from blocking AK/AA, but I think the improved equity when called makes up for it, and I also think that even though Axs has the effect of blocking AK/AA, it also blocks the Axo combinations that people tend to 4bet bluff with a ton, so its sort of a wash.
