You can't put it back in the box. Once an abusable capability exists, it will be abused. The most effective time to try to create a pervasive surveillance system is when people are afraid. Also, there's no evidence that a more invasive system is "more effective". If a privacy-preserving system is equally effective, there's no valid argument. And in any case, if a privacy-preserving system is effective enough to get community transmission under control (bringing R below 1), that may suffice.
