So, the government should "help" them, right? After all, "it takes a village"...
The government has a duty to protect citizens from external enemies and internal enemies. Libertianism is a utopian philisophy that will never work in the real world.
Better minds than yours have figured it out. How about Edmund Burke, the philosopher who greatly influenced many of the founders of our country:
"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
And Thomas Jefferson, known for his wide ranging intellectual searchings, and not known for slavishly adhering to a particular doctrine:
"Reading, reflection and time have convinced me that the interests
of society require the observation of those moral precepts ... in
which all religions agree." --Thomas Jefferson
But all who want pornography, and they want it now, will continue to not listen. Such is life. There are none so blind as those who refuse to see and keep their eyelids tightly shut no matter what.
