[Bioshock Infinite] Shouldn’t Booker have the ability to open Tears as well?

In Infinite, we learn that Elizabeth can open tears because her cut finger is in another dimension.

With this logic, shouldn’t Booker have the ability to open tears as well since he bleeds from combat/sheds hair and skin cells in different worlds when he and Elizabeth travel to new dimensions over the course of the game? (A dimension where the Chinese guy’s tools are back at the shop/A dimension where Columbia is an underwater city named Rapture instead)

I see it as a combination of two factors.

First, Elizabeth has had her abilities since infancy, so she has had years to practice, and her brain may have even developed in a special way that gave her more control.

Second, her injury was directly inflicted by a tear, so her nervous system was in direct contact with the space the between worlds. Though it's worth mentioning that you don't have any muscles in your fingers  so it's not a simple as saying that the motor nerve that used to control her pinkie, now controls her powers.
