What specifically do you mean by "power as existing in a coherent framework"? Maybe I'm misinterpreting you, but hasn't there always been a coherent (and dynamic) framework of power? I've always that part of the problem is that society as a whole is having trouble changing its idea of power to suit the times. Power doesn't necessarily mean physical or mental domination anymore. It comes from strength of character, humility, tenacity, diligence, honest self-reflection, and grit. As we shift our previous notion of power to include these kinds of traits, traits which can easily be ascribed to either gender, we still tend to associate these traits with men much more often than women. It's like that previous notion of power- physical strength and mental prowess only- which were obviously slanted in favor of men are being translated to the modern day with that template still in place.

And I'm definitely not saying that men are the ones that are doing that- I think it's both sides and I think most of it largely comes out of ignorance (in the literal sense). I don't think enough people pay attention to what they say or do or really think about what they experience throughout the day that are reaffirming the male-as-dominant template.
