Pedophiles will always exist. It's the unfortunate truth. But if we can reduce the amount if children subjected to sexual assault or rape then we should absolutely explore it. That's what this article is about. Removing the stigma for treatments that you accurately described as a barrier. How successful this approach is remains to be seen. But it's a worthy and sound discussion to have. And who knows, if it kicks off maybe we can even have people treat it before they actually hurt a child. It's a big maybe and will not happen for long time but we can try and make steps towards that goal.

There are more extreme methods such as chemical castration, sure. But that has its drawbacks as I mentioned in my comment above.
