I think that Cory Doctrow showed the ideas of anarchism in his book, because of the overall anarchial sense that can be felt from reading the book. Marcus's opposition to the government and overall distaste to the authortative figures in the novel help set the what can be seen as an underlying tone of anarchism. Government control is seen as negative from Marcus's point of view in the book, and the final touch of purchasing an Emma Goldman poster shows how close Marcus is to showing that he is an anarchist without actually stating it.
