I have also started reading, 'The Virtue of Selfishness', a later book that outlines her philosophy of Objectivism (with which I was not familiar).
First impressions are that the ideas are intelligent and well thought through. I am not yet sure where or indeed if she draws the line, in other words where she agrees (if she does) that causing harm to others restricts the individual's freedom.
I would not be at all surprised if Neoliberals in the USA had taken 'what they needed' from her philosophy, to serve their own ideologies. It's what they tend to do, imo. They arguably took Martin Luther King's saying that people should not be judged by the colour of their skin, but by the content of their character, to justify what some have called a new, subtle form of colourblind racism.
