The aim isn't just prosecution, deterrence and reducing ease of use is an aim. And self selecting by choosing a service that only hosts CP makes it like shooting fish in a barrel when you do roll the admin/server. Ask "freedom hosting" and some Tormail folks about that. I was actually really surprised at the time to see the site that hosted my favorite OCR tech pdfs- yes, mega, was pretty obviously allowing forums to flourish under it's nose. Maybe there was too much content for them to check or maybe they didn't care. Yes, the investigator's job get's harder but not having this material turn up in effectively mainstream environments is a good thing. I'm technical rather than investigative but good investigation + sloppy OpSec breaks the veil of anonymity, technical brilliance rarely does. Those barriers you are thinking of- they have always existed in meatspace. Digital space is a cornucopia of evidence in comparison.
