I don't know what to say. This is one of the most bewildering things I've read all day. You do understand that encryption in its current form is all thanks to the government's creation of digital cryptography through ARPANET projects going back 50 years? For instance, the TOR network was created by the Navy to provide secure transmission channels for submarine communications. Now it's used by hackers and pederasts alike, but you bet your ass the Navy still uses the technology!
Cryptography has been around for millenia. It's ALWAYS been used to evade, the law or otherwise! In your world, would everyone would be issued a secret decoder ring that they'd have to turn over to the police when they're arrested? Clearly you have no idea what you're talking about or you were drinking when you posted.
These rants that everyone’s always been able to easily evade the law are bemusing.
