My point was that the distribution of the material, especially free of charge does not necessarily encourage further abuse, nor does its possession. I do not know, though I admit that I suspect that the abuse would be encouraged because it is being paid for.

Edit: In my opinion, the following offences ought to exist with relation to child pornography and abuse:

(1) Child abuse is an offence as it currently stands, or with revised ages of consent to better reflect philosophical, scientific and psychological evidence (2) The act of recording of abuse with majority or express intention of furnishing the material for charge or otherwise in order finance or encourage continuing abuse is an offence

I think the second part needs some elaboration. I don't think that recording a certain act taking place ought to be illegal, nor I do I think it ought to be illegal to share that material with others. However this presents a dilemma: the abuse may be encouraged by the fact that the material is being sold or even enjoyed. If this encouragement to continue abuse can indeed be proven in a court of law, by some standard deemed appropriate (either the standard 'beyond a reasonable doubt' or the more strict 'balance of probabilities') then the act of making the recording and the act of furnishing the recording, I believe, ought to be an offence.

On the other hand, if the recordings are made merely to provide the enjoyment of others, and not for the purpose of encouraging abuse, I do not think there should be an offence.

At the risk of over-emphasising the point: A child abuser may be encouraged by (i) money (ii) the thought that people are watching the recording (there may be further motivations).

If it can be proven that abuse continued and the abuse was contingent on one or more of these factors, there is sufficient reason to believe that the intent of the recordings aided another crime, which I think may be sufficient to culminate in an offence.
