This does not apply to pornography. Someone with a morbid fascination with porn may spend his (Or her) time looking at it to the exclusion of other, more productive activities (Like work) but stopping causes no trauma and can easily be effected by simply making the decision to do something else.
In the end most so-called addictions are really a matter of an individual making the decision, or not, to continue. In any case, its none of the government's business.
I believe you are addressing the wrong post. Mine was:
An addiction for which there is no cure, thus the outrageous tragedy to introduce it to young, curious minds.
Once something is SEEN, the mind can never forget, and the rest you go figure, hence the Jeffry Dommers (spelling?)of the world. The Internet should hang its head - biggest money maker is porn.
However, I agree with you, the government has no business in this one.
