You've been talking to different libertarians than I have.
It really seems like you don't have a concrete idea of what libertarianism and objectivism are. The hedonistic libertarian and the strict religious libertarian will argue for almost the exact same thing. As will the objectivist. The point of libertarianism is that it doesn't matter what you believe, you don't have the right to force your ideas on anybody else. Let people be free to do what they want so long as it doesn't infringe upon the rights of others. Many libertarians are also very big on property law and economic freedom. Objectivists hold the same values, but for differing reasons maybe. What I'm saying is that the reasoning behind what they want is 100% completely, absolutely irrelevant. They both want more or less the same thing. Freedom.
