It was my understanding that 18 U.S. Code § 871 included depictions enticing or encouraging such acts.

If that's the case, I suspect that the relevant language here is enticing or encouraging. Depictions of, say, historical events would be different. That said, I am most definitely not a lawyer.

This is my understanding as well. But we're going to need to come back later with some input from case law.
