Using the encryption argument: Encryption is a solved problem. Easy to implement solutions are available everywhere. (yes, post-quantum cryptography is not yet solved, irrelevant for the current discussion). That means that even if it were technically possible to create "legally-breakable-encryption", criminals would simply use real encryption and law abiding citizens would be stuck with broken "encryption" and be vulnerable to government surveillance... and to said criminals. I.e.: there are only downsides. And government experts know this just as well as anyone. Which makes their agenda very clear. More in general, imho, the benefits have to outweigh the costs: even if breaking all encryption would have offered a small benefit in fighting bad guys, that still does not outweigh the costs of a total loss of privacy (think china) for everyone.
