I am of the opinion that active pedos are rapists pure and simple. However, when the only outlet at all is child rape, then society is failing those encumbered with this "mental" problem and their victims.
While society is definitely failing their victims, I have absolutely no sympathy for rapists and child molesters. I don't care what kind of "mental" problem they have.
Well I put mental in quotes, since psychotherapy is the only "treatment" which if pedo is a hardwired sexual orientation might be as effective as "praying the gay away". It's possible that it could be effective in the situation of an abused child becoming an abuser though.
I think we only have studies done on actual abusers, which is something of a problem, since to my mind there could be three classes, "hardwired", "abused" and "amoral psycho who just didn't care victim was a child". 3rd class there is a complete wildcard, hopefully rare, no measures will be effective. However, within the first two classes, we just don't know how many turn into actual abusers, and how many are possessed of enough self control and social responsibility never to act on the urges they have. What I would expect, is that if victimless material is available, more of them would be empowered to self regulate vs the sealed pressure cooker effect. Possibly the second class, could "work through their demons" themselves somewhat. Which may be necessary, because I have heard that in some areas, it's impossible to get "treatment" for pedophilia, without actually being convicted of doing the act. Anyway, we've practically made pedophilic tendencies a "thought crime", you have those thoughts, you are evil, hammer that idea home long enough and someone cursed with it will have their ego shatter and reconstitute itself with "Yah, I'm evil then, so what, means it's not my fault, can do what I want". You can see where that leads. I would think the better message to be "Acting on those thoughts is evil"
Anyway, hauling it back round to how bitcoin might have anything to do with that, is, if tightly repressed as a "thought crime" in all regards, those with pedo tendencies might have a high chance of "blowing up" and acting, say 50%. If instead allowed victimless outlets, art, sex dolls, stories, that bitcoin might allow them to buy without stigma, then the chance of acting against a child may be significantly reduced, say down to 10%. If in the random course of life, I knew my children were 10% likely to come across a pedo, I would far rather that it then be 1% likely that he harmed them, than 5% likely... Whatever the figures may be, bigger figure bad, smaller figure better. Since child abuse may have a snowball effect if unchecked due to some abused becoming abusers, even small reduction is going to be very beneficial in reduction in future generations. While I would find it distasteful if a public figure was outed as having a child sized sex doll, I would be hopeful that meant that that had kept him a functioning respectful contributor to society otherwise, and not an active abuser.
All in all, we either have freedom of expression or we don't. If "just this one thing" is a thought crime, pretty soon it will have company. To be completely clear for those who might get all emotive and go off on one, I am not advocating child abuse, photos using actual children or anything like that. Why do I seem to be engaged in the topic? Well let's just say that circumstances occurred several years ago where I had to do a hell of a lot of real world practical thinking about it.
