I have not read the actual essay, but it matters little because my opinion on the matter has long since been established.

My stance is generally possession of 2D should be legal, while real children porn should be illegal, only because those who produce it tend to make money off those who obtain those materials, creating demand. That said, I think the penalty for mere possession should be much lighter than actual production, something like a fine (definitely not jail time or openly labeling them as deviants to be burned at the social media stake). The idea is to discourage people from supporting that industry, but let's face it. Illegal or not, people who WILL venture out and risk themselves to get this content WILL get this content.
