I agree. The problem with the girl-power-as-female-man-power trope is that it relies on the definition of fragile, power focused masculinity as the trope for agency. By this assessment, any agency must be somehow rooted in maleness. It’s bullshit. As to the getting hit on the head thing, there’s a fine line between knocking someone out and a skull fracture that kills them. No one ever seems to accidentally kill the guy they meant to knock out with a fire extinguisher.
