Libertarians advocate maximum individual freedom, initiative, and self reliance. Which means absolutely minimalist central government. Although, as I stated above, conservatism holds the moral ground, I do not believe government either can or should try to legislate morality in any way, shape, or form. Cage felons and repel foreign invaders and forget everything else. Don't even pay remote lipservice to any of the dead manifestos of collectivists.
Anarchism is the farthest point on the scale of the relationship of the individual to the state.
Because anarchism advocates all individual and no state whatsoever. No government no nothing. This is unrealistic for anyone who understands human nature.
