In York v. Ferber (1982), 458 U.S. 747, 102 S. Ct. 3348, 73 L. Ed. 2d 1113, the Court upheld a prohibition on the distribution and sale of child pornography, as well as its production, because these acts were ' intrinsically related' to the sexual abuse of children in two ways. Id. at 759. First, as a permanent record of a child's abuse, the continued circulation itself would harm the child who had participated. Id. Second, because the traffic in child pornography was an economic motive for its production, the state had an interest in closing the distribution network. Id. at 760."
