Yeah, the point I was trying to make, is that having a real, anonymous digital marketplace might be very useful to intelligence agencies, so it might make sense for them to help build one. Without looking to build in back doors - just like naval intelligence might want an onion router system that works, and has enough traffic going through it that picking out the (smallish) sub-set that is intelligence traffic isn't trivial (eg: a traditional, secure, encrypted (overlay) network that is only used by a single/handful of intelligence agencies isn't very robust/useful for hiding communication).
