The issue is also with "appearing to be under the age limit" if you are portraying a person under the limit this is also against the law in america (please correct me if i'm wrong, this was my understanding of US law)
They tried that, but the law was struck down in the courts. I remember someone pointing out that it could be theoretically applied to works of fiction like Romeo and Juliet because it involved minors. You see, wikipedia says so:
"Simulated child pornography was made illegal with the Child Pornography Prevention Act of 1996. The CPPA was short-lived. In 2002, the Supreme Court of the United States decided Ashcroft v. Free Speech Coalition, holding that the relevant portions of the CPPA were unconstitutional because they prevented lawful speech. Referring to Ferber, the court stated that "the CPPA prohibits speech that records no crime and creates no victims by its production. Virtual child pornography is not 'intrinsically related' to the sexual abuse of children.""
