"More insidious, though, will be the _next_ level of action, which will make it illegal to use any genuine form of encryption."
That's what I think will be next. If you make the MERE USE of encryption (outside of State-sanctioned schemes) a criminal act, then you reduce the possible outs to steganography, which can still be severely limited (as in you can only watch so many cat videos a day before it becomes suspicious, nonsense or outlandish posts will raise red flags, plus images, videos, and text can be mangled, bleached, and so on to reduce their steganographic usefulness).
