Your oversimplifaction of the article notwithstanding, it raises an interesting point that treatment for many things is available before an act is committed, but pedopilia we don't even try to treat. It's actually screwed up.
We should try to treat people who feel the urge to act (but don't) AND AT THE SAME TIME, punish actors with the harshest penalties possible. And that's where the article's title "Pedophilia a disorder, not a crime" gets it totally wrong.
