That just becomes an ever-escalating arms race. We need to invest in political and social systems that regulate the use of technology, not imagine that we'll overcome the dystopian use of technology by applying yet more technology.
"Reamde" has multiple cool ideas (the miasma, basically our dystopian internet information sphere we live in today), but one of them is people walking down the street with glasses that have some kind of light device that shines on your face to confuse facial recognition.
Encryption, for example. It denies the government information, evidence. There's nothing it can do about that. So will it criminalize encryption itself? Will it presume guilt if you refuse to decrypt? Will it ban free computers that run software not signed by the government?
After enough iterations, we'll either end up with an uncontrollable population wielding ubiquitous subversive technology, or an omnipotent totalitarian state that defeats any attempt at subversion before they can develop.
I hope for everyone's sake that the governments will discover their own limits before either outcome.
as political changes are incredibly slow, in the meantime we need to make it harder to collect
