The harm is indirect, but caused by the market for said video.
So... how about cases where someone just downloads a copy off the internet for free (and I mean absolutely free, not a quid-pro-quo exchange--a complete stranger downloads the video and has no further interactions with the provider)? Or when someone posts a copy for free download by complete strangers on the internet? That seems to bring no benefit whatsoever to the initial producer. (It's possible that the video or picture could come with "Made by <name>, send donations here" or something, but I'm sure that's not the case most of the time.) Would you be in favor of legalizing free online distribution of unattributed child pornography, then? If so, please recognize that this is at odds with existing laws (although your position would at least be self-consistent). If not, please explain yourself.
Also, the owning of the object e.g. ivory is not illegal; the selling is illegal, right? So a little off the mark there.
I see, you're right. But the effects--ruling out legal producers as competition, and raising the price on the black market--are still the same kind, just probably less pronounced and less likely to catch civilians in the crossfire. And, again, it seems to mean that your argument doesn't support the criminalization of possessing or freely distributing child porn. (Also, no objections to child porn whose production demonstrably caused no harm to the child? Perhaps you'd even assent to "the burden of proof is on the prosecutor to establish that a child was harmed", rather than "the burden of proof is on the producer to establish there was no harm".)
My position is consistent in this way: as a culture, we condemn child pornography. We go through some considerable theatre, arguably more or less effective, to quash it. The premise is, it causes harm to children to be involved in highly-charged emotional situations that are at the very least profoundly confusing to them, and at worst cause lasting damage. It has been deemed by legislation and executive order to be worth suppressing the trade, even if only to make it perfectly, publicly clear that it is considered abhorrent.
As for harmlessly filming a child remotely, I can think of no greater invasion of privacy. Children cannot conceivably be capable of being said to consent to such activity. The damage may actually be done years later when they inevitably discover the betrayal and indecency they were subjected to.
