"'However what about women who are willing to throw themselves at these men and would do so without coercion?'
This makes no sense. Think about it for just one small second. If an actress had the option of competing fairly for great roles that she could get or lose on her own merit or ending up in a situation where she could get a mediocre role that pays less than all the men but in order to get it she'll have to allow a repulsive man to wank into her body, which do you think she'd choose? Do you think there is any free choice in a situation where someone more powerful than you has what you want and is willing to exploit your desire to get it?"
I think trully free choices are vanishingly rare for men or women. In fact that's part of the whole point. People pursue power, wealth and fame precisely because they afford you more choices.
Furthermore I'm not seeing Greer's as an either/or proposition. It's fine and indeed desirable to have your Me Too movements that promote solidarity amongst women. A safe space to come together and recognise that what happened was corrupt and very wrong.
The issue is if that is all that happens it will fizzle out and precious little will meaningfully change. What needs to happen is something like a class action lawsuit against SAG (Screen Actors Guild) I would say it is a racing certainty that some women somewhere took their concerns and grievances to the the organisation they have to be members of and pay dues to that is supposed to represent their interests in the industry.
What you would see happen if the SAG took a drubbing both reputationally and financially they would be shit hot and incentivised to ensure there was NEVER any repeat Weinstiens, and if there were they wouldn't last long. Also if male actors sexually exploited women and could be expected to be kicked out of SAG (thus limited the work they could get) it might make them think twice.
This won't happen as too many powerful men (and some women) are too invested in the current corrupt system so this whole thing will be a flash in pan that will probably dominate a few news cycles in 2018 but not a whole bunch more than that.
