I don&#x27;t think that would be the case. If a couple of western Governments &quot;ban encryption&quot; it would probably just mean that they weaken the crypto (e.g. backdoor). The traffic of weakened crypto still looks the same as the traffic of strong crypto - I don&#x27;t think it would make strong crypto any more noticeable.<p>Also remember that crypto would still be legal in the rest of the world (China is not going to backdoor their crypto for the NSA&#x27;s benefit) so you would still have heaps of encrypted traffic moving across the internet. I doubt that such a measure would do anything but make mass surveillance of western populations easier.
