A part of the explaination about this anecdote that mays seem peculiar, and totally unexpected when Hank Rearden meet with Ragnar Danneskjold on a desterted road at night, is that Robin Hood is considered as part of the realm, as a symbol, of the New Left--he is dressed in full green clothes, he lives in the woods and as such he embodies the concept of raw and savage nature by opposition the realm of machines, complexity, science, etc
You, and some person explain why, in fact; and Ragnar Danneskjold, first and foremost, explain it quite well withpout any ambiguity. Ragnar Danneskjold is the exact opposite of Robin Hood. But perhaps the difficulty to se this lie in the fact that, in the story of Robin Hood, the rich is innescapably the vilain, and the poor is not really involved in any conspiracy scheme.
