You might counter: yes but why shouldn't we add this, if we can easily stop people from counterfeiting money, leaking documents, flying drones in restricted areas and so on. It's so convenient that we can stop this with a bit of technology. We'll, it would be convenient if we could compell people to testify against themselves or their families, or if we would open and scan all mail, or require priests to report confessions to law enforcement. Yes, we could reduce some crimes this way, but we deliberately chose not to. It's a matter of weighting the interests of law enforcement against a basic feeling of "trust" that you have inside a society.
I always thought of personal liberty as the value from which other values derive. For example, the law exists to protect our rights (the right to life and the right to property being the most obvious examples) from bad actors. Social welfare and socialised healthcare restrict the damage that personal catastrophe and random chance can do to our freedoms.
I'm always less inclined to believe that it's a few powerful people, and more inclined to think it's a cultural war between memes (in the Dawkins sense). People are driven by ideas. If powerful people are contributing to a cause it's probably because they are under the influence of a meme. That, or a more Machiavellian reasoning like trying to purchase social capital.

Remember to act surprised.
