You can't talk to most political Libertarians about Anarcho-Capitalism and expect to get anywhere. It's relatively easy for Mr. Klien to sell his project to political Libertarians because it's pitched at a level only slightly above theirs. Instead of changing the system, we build our own country on the sea with our own political system. I must emphasize that there's nothing wrong or inappropriate with political Libertarianism or Mr. Klien's project. Freedom expands as the cumulative result of many different strategies and tactics.
Different audiences are ready for messages at levels appropriate to each.
In attempting to communicate freedom, we need to be very aware of the level of our audience. Investment Buying into a system is an investment. In a way, jumping out of a system involves writing off the investment. All along the levels, people invest in the systems they buy into. The political Libertarian invests in the form of paying taxes and feeling bitter about it, contributing to the cause, and working without pay.
