Youre literally making the argument that there are not "tops" or "bottoms".
Even in gay relationships they know who is the Alpha partner, and who is the beta.
Because you dont comprehend this fact you think the Alpha and Beta dynamic is bullshit. Alpha just means an Alpha partner. One who leads, not one who is led. The dynamic of males and females has always been an Alpha (dominant male) and beta (submissive female). Thats how its always been in dominance hierarchies.
