Here in Germany, we have banking trojans wehich are able to thwart two factor authentication by SMS. This requires considerable skill in synchronizing between the hacked computer and the hacked smart phone. I am pretty sure these guys can come up with decent encryption implementations if these are not available as open source any more. And the latter is pretty unlikely. In the 90's all but the US people had strong encryption after all. Open source projects working on crypto where just moving off-shore.
A ban of end-to-end encryption will need to be enforceable. What will LEO do, if I come up with it? Bust my house? That's unthinkable in Europe. Enforceability also means that all communcations must go unencrypted. This merely would kill all online commercial activity.
It would make it much easier to avoid DRM, and to cheat in online games for sure. I'm guessing online gambling would be out the window. Also, I don't know if I would want to do any banking online.
Well that can "easily" be solved by giving you a private key to use for your banking and e-com usage. Then "they" can decrypt it with ease and you stay "safe".
