Fully agree but I can tell you about point 1 that there enough gullible scientists in the world that see nothing wrong with the current system.

They will gadly pick up free review when Nature comes knocking, since its "such an honour" for such a reputable paper.

Something else we can do: regulate. Like every other corrupt industry in the history of the world, we need the force of law to fix it--and for pretty much all the same reasons. People worked at Triangle Shirtwaist because they had to, not because they thought it was a great place to work.
