I did mention the possibility for this speculative correlation to be observed from the very first time I mentioned PIR. I agree that a person could use this technique to speculate on the demand for CP, probably with decent accuracy at that. So what if we remove the financial aspect then? Are you against legalization of CP distribution and possession, so long as there is not a financial aspect? Also, if people pay a fixed price for access to the PIR system, then there will not be price fluctuations correlating with the introduction of any particular material, and thus the demand could still be masked even with a commercial model. Government wants to enslave people "rationalization" is not used by pedophiles , most common amongst libertarians and anarchists I would say. Actual pedophiles (not all CP consumers) tend to stick with the tried and true "We are like gay people" and "Who gives a fuck about children anyway?" rationalizations. You are confusing separate issues. I do not think it should be illegal to shoot a gun. I do think it should be illegal to shoot a gun at an innocent person. I do not think it should be illegal to pay for the possession of any large number. I do think it should be illegal to pay for the molestation of children. I don't think it should be illegal to count up to infinity. I do believe it should be illegal to molest a child and take a picture of this molestation, in order to obtain a sought after number without having to count to an extremely large number (or for any other reason). I find nothing morally repugnant with downloading ANY large number, however I do find it morally repugnant to pay for the molestation of children, or to molest children. There is a difference! In fact, there is a large number that will create the exact same photograph that would be created if any given child was molested on camera. I think paying for a childs molestation in order to obtain this number (or for any other reason) should be illegal, I think that molesting a child in order to obtain this number (or any other reason) should be illegal, I do NOT think that obtaining this number should be illegal. As it stands today, if I run a random number generator, and by some extraordinarily unlikely (but entirely possible) chance it outputs a CP image, my possession of the output image is as illegal as if I paid for a child to be molested! This is insanity, there is nothing immoral about running a random number generator and keeping the output, there is something immoral about paying for a child to be molested! The original thing that you called a math exercise, was my suggestion that you should not object to CP being distributed via PIR as it masks demand. CP distributed via PIR is a math exercise, CP is a really large number and PIR is a mathematical formula for being able to obtain numbers from people without them knowing the numbers you obtain from them.
