Sure, that might lead to a dystopian future or something, but you can’t ban it.
I know the intention was, "You can't ban it, because to do so would prevent progress - something we all agree is important," but I...actually agree with the words, not the meaning.
It might lead to a dystopian future or something, but you can't ban it because no one in power wants it banned. Even if we did ban it, some other technology would develop to sate the desire to take people's privacy away from them. You can't ban it because it would prevent progress, something the people in power view as important in an economic system based on infinite growth. The right to privacy is a battle that will never be won. This dragon will never be slain, because the technology isn't the problem - it's the people demanding its existence, and their ever-increasing ingenuity when it comes to thwarting our rights.
