The problem here is... just viewing the picture is creating a 'demand' for such material, and therefore a supply must be created, which exploits minors. I'm not really on board with the drawings of such things being forbidden as well, that seems like overkill to me, and drawings may supply the consumers of such materials that aren't exploitative of minors. It's an ugly nasty situation for sure.
Not necessarily. Certainly if someone's paying for it, they're going to incentivise production. But at the other end, there's the situation where someone's downloading it off a server which isn't counting the number of downloads or isn't telling the provider, which is often going to be the case when, for example, it gets spammed onto third-party imageboards, in which case people viewing it aren't affecting the outside world in any way.
And consider. So downloading child porn off P2P services, which is a way of viewing such material, that increases the incentives to make it? Well, downloading copyrighted material off P2P services reduces the incentives to make it, as the copyright lobby loves telling us. These two things don't sound very consistent.
As Slashdot loves noticing, the normal rules of supply and demand don't apply to information when you have this almost infinitely efficient machine for copying it called the internet.
So when the poor fail to cross an additional hurdle of saving for something which shouldn't be necessary whilst not having enough money to feed themselves properly, which the wealthy don't need to worry about, or simply refuse to go through such unpleasantness in order to obeise themselves in front of the systems which oppress them, you accuse them of lacking self-discipline, and use that as an excuse to deny opportunity from them and keep participating in their oppression.
A perfect example of why suit culture is not just unpleasant, but is actively evil, and anyone ethical should help resist it.
