well, for example, you could roll your own secure messaging over WebRTC data channels using Web Crypto. There won't be anything unusual looking about the traffic as it will all be wrapped up inside DTLS/SRTP which is the transport for WebRTC. so, it's encrypted twice and would look perfectly normal to any outside observer. there's no way to tell what is happening in the messaging layer WebRTC "encapsulates".

At end of day, if someone wants to do this, there is no way, afaik, it can be detected. so, all these laws won't really help combating serious criminals who have some savvy.

The way to do it would be to outlaw any protocol that can encapsulate to a point that off the shelf DPI can't read it.
