My understanding of Ostrom's work was to show that basically almost all commons were managed, and that when they were not, that was the result of selfish actors deliberately seeking to dismantle the management structures to further their own individual interests.
That was not my understanding at all. She seemed to be making a much more nuanced point than the simplistic: "selfish actors deliberately dismantle..". I was more responding to the idea that she refuted hardin though which is very much not the case. She built on and expanded his thesis.
