I would argue that although the advance of technology makes mass scale surveillance easier, it also makes it harder to hide. Secrets are harder to keep now, and that cuts in both directions. I think banning mass surveillance wouldn't necessarily be futile. With vigilance and enough political will, such a ban could be enforced and maintained. Also, there are also other technologies that can affect whether or not mass surveillance is practical. Cryptographic tools like Tor and Bitmessage, represent another technological advance that can only be delayed.
