Vlad, imagine a content distribution system where it is cryptographically impossible for anyone to know how many people are downloading a particular file. This is called private information retrieval. So, you think that if a pedophile accesses CP via PIR, it is okay? Because it is impossible for the uploader or anyone else to know if anyone requested to download the CP, so the demand for CP in a PIR distribution network can NOT directly lead to more production, as it is impossible for anyone to determine ANY INFORMATION about the demand for CP via analysis such a system.
