Have you read Atlas Shrugged, Treg? Those who have, will understand the moral revulsion one feels at having your life's work sucked away by the leeches who proclaim their need as a claim on your life, to justify stealing that which you have earned.
If you're looking for a gut-level emotional appeal against tyranny and in favor of individualism and liberty, there it is. It's much more than mere "selfishness," wishing to keep what you've got -- it's a fundamental sense of justice, a feeling that it is morally right for each person to keep the fruits of his own labor.
Atlas Shrugged probably has hooked more people into the philosophy of libertarianism than any other book, because it does provide a moral sanction for liberty. Theistic religions spend a lot of time preaching the virtues of charity and kindness, but they notably do not give a strong defense of a person's moral right to keep and use what he has earned for his own private purposes. Rand does. So I'd say Atlas Shrugged is a good candidate for your "master freedom narrative." But recently I've found a better one: Larken Rose's new book, The Most Dangerous Superstition. Read my review of it on Amazon.
