When Biscuits asks Bojack if he really believes he didn’t have power in his relationships with all the women he hurt, he responds “I am an addict, one of the first things I had to accept was my own powerlessness.” This is a reference to step one in 12 step programs (“We admitted we were powerless over alcohol/drugs, that our lives had become unmanageable.”) Bojack of course grossly misinterprets this step, showing that he hasn’t actually learned anything.
