Re: a technical solution surely exists
Yes, use weak, therefore useless encryption standards that aren't so hard to crack. At which point you may as well have handed cybercriminals, including Terrorists(tm) and state sponsored bad dudes at which point you have just handed a loaded nation-state size gun to China, Russia and the rest with an instruction that your financial and critical infrastructure is not wearing kevlar today.
You cannot insert a "back door" into mathematics, which is what Crypto is, essentially. Any politician who tells you otherwise needs to step the fuck away from the TV, this isn't crime fiction.
Also: Technical problem? Really? The simplest way would be for the NSA/GCHQ to SSL middleman the in-and-out pipes to the various POPs and done.
