People who already have power do not need props and schemes, because, well, they have power. I know that if I grab my boss’s crotch during a meeting and he says ”you have thirty seconds to convince me not to fire your sorry ass right now”, every witness to the event and everybody above him in the corporate hierarchy will back him up.

A man tempted to do the same thing to a woman less powerful than himself does not have the same assurance that he will suffer consequences for his bad behavior, and you can’t just create that sense of assurance by fiat. (As the Readercon debacle indicated, even written policies are no guarantee.) So people of good will are still trying to figure out how to hack the social environment to achieve a better culture, and until the rules of that culture become second nature to us all, then those social hacks will seem like, well, hacks.
