> What is the rationale behind defining child porn age < 18? You are conflating two concepts that aren't relevant. 1) Dating and age of sexual consent have nothing to do with the legal rationale behind child pornography prohibitions. 2) Depictions of nudity of subjects under 18 do not run afoul of child pornography prohibitions (of course, contingent on if you can afford your rights all the way past appeals court) The age in 2) is typically standardized by the federal government, and they just let people consent to contracts to exploit themselves at the age they can consent to any other contract.
