Ah, the standard libertarian fantasy. "Let people make their own decisions!"
Libertarians are romantic Republicans; they think that mankind was born good and that civilization makes him bad. Wrongo. "Man is Born Good" is a slogan over every commie mass grave in the world. But Man is not born good; he is fundamentally evil, and needs society and law to live a decent life.
And one of those laws is to keep a certain green leafy substance off of the grocery store shelves so that stupid fourteen year olds can't all get stoned all the time. Deal with it.
