“There is value in dissent. And, perversely, there can be value in lawbreaking. These are both ways we improve as a society. Ubiquitous mass surveillance is the enemy of democracy, liberty, freedom, and progress. Defending this assertion involves a subtle argument—something I wrote about in my previous book Liars and Outliers—but it’s vitally important to society. Think about it this way. Across the US, states are on the verge of reversing decades-old laws about homosexual relationships and marijuana use. If the old laws could have been perfectly enforced through surveillance, society would never have reached the point where the majority of citizens thought those things were okay. There has to be a period where they are still illegal yet increasingly tolerated, so that people can look around and say, “You know, that wasn’t so bad.”
