Right "libertarians" (whether or not they are members of the Libertarian Party) have very little in common with anarchists. Many (maybe most) are "minarchists" meaning they advocate small states rather than no states. Compare the "small government" rallying cry of the Republicans, often advocated but rarely attempted. Some right libertarians call themselves anarchists, meaning they oppose the state. Overall, libertarianism is mostly a holdover from classical liberalism. Its political philosophy is drawn from a lot of the bourgie Western political philosophers, with some recent developments. Anarchism initially borrowed a bit from classical liberalism and state socialism, but has developed into quite a constellation of very different political paradigms. A lot of libertarians embrace the Austrian School of economics. There is no school of anarchist economics (a positive project), though some embrace the Marxist school and others reject it. There is only the opposition to capitalism held in common by all anarchists, which is anathema to right libertarians.
Anarchism seems to question the fundamentals that most other political philosophies are based on, including libertarianism. It seems possible that there could be some ideas or concepts worth appropriating from right libertarianism, but we should be careful to be VERY SELECTIVE about what to borrow. In order to do this one must first study the principles of both right libertarianism and anarchism in great detail. If one undertakes this project they must be careful in order not to contaminate anarchism with hidden authoritarian ideas. There seems to be some interesting right-libertarian writings on the topic of coercion. If we want to convert right-libertarians, we might try to write a polemic demonstrating how capitalism is coercive.
Overall it seems like we may benefit from limited, brief and strategic alliances with right-libertarians. However, this could also backfire if non-anarchists perceive anarchists and libertarians to be associated. I'm also skeptical that a hostile confrontation with Tea Baggers is a useful tactic, either. Antifa is a wonderful tactic, but doesn't apply so well to right libertarians who are skeptical of the state (or government) and are not uniformly racist.
