Generally Libertarianism is outgrown. Not always, of course.
Freedom? Here's a good description:
"Men are qualified for civil liberty in exact proportion to their disposition to put moral chains upon their own appetites--in proportion as their love of justice is above their rapacity;--in proportion as their soundness and sobriety of understanding is above their vanity and presumption;--in proportion as they are more disposed to listen to the counsels of the wise and good, in preference to the flattery of knaves. Society cannot exist, unless a controlling power upon the will and appetite is placed somewhere: and the less of it there is within, the more there must be without. It is ordained in the eternal constitution of things, that men of intemperate minds can not be free. Their passions forge their fetters."
-- Edmund Burke
Yup, and then you die with that much less of a life worth living.
