Libertarianism basically just means weakening your country into a feeble, defenseless state so a non-libertarian entity can come in and destroy you or enslave you. It's just a power vacuum to be filled by a strongman. Whether you think it's real or fake, this is what the protocols of the elders of zion are about, a recipe for weakening a nation to then take it over or exploit it.

It's kind of hard for the world to practice disarmament if only one person refusing to gets to automatically take over by default. There is no such thing as anarchism or "no government". Power vacuums are always filled by some strongman. The best you can hope for are small, more localized govt and abolition of federal, non-localized, non-representative ones.
