Ayn Rand was a minarchist. From my understanding she felt that society was best served by having the elites determine the direction for society, not so much dictating but guiding benevolently. John Galt came to the conclusion in "Atlas Shrugged" that society had gone too far and that the elites were being crushed by the collectivists. This is why he removed them from the mainstream to a secret location, with the exception of his old mate Danneskjold whose job was to destroy the world so that Galt may rebuild it. It was always Galt's intention to return to society once the old structures had been torn down. Humans will always be human, that's why there are groups of people out there now building decentralised systems that can sidestep some of the less savoury aspects of human nature. Some of these are minarchist, many of the original designers were anarchist. I'm certain Rand wouldn't have approved of their projects. Most people are good, centralised fiat monetary systems make it more challenging for the "good" people to live moral lives.
