in one way, governments regulating pornography is worse than the drug war because at least in the case of the drug war people can agree on what cocaine even is. There is no consensus on what pornography is. It would be like if the government decided to regulate “junk food” and then defined junk food as “food which appeals to the glutton’s hunger”.
The most famous quote wrt what pornography is centers on the phrase “I’ll know it when I see it”
