I'm not sure I understand Simulacra. I get the idea, just spam devices around the area in hopes you're lost in the crowd. But anything designed to track you is purpose built to handle tons of devices moving about. Maybe if everyone had one in their pocket we could overload the surveillance devices, but at best you're just bloating their logs.

Simulacra is meant to send out signals that look identical to other real signals making it harder to decipher what's real vs what's not. The unique identifiers of those devices show up and never show again once they churn. They have a fresh set of identifiers each time one is produced. Its never going to be perfect but if you can hide the real stuff in a ton of fake stuff it offers a level of obfuscation that otherwise wouldn't be there.

Seconding this, plus, the original devices stays always visible to the tracker? Does it really matter if there's your sole device in the range, vs always-present yours + ton of noise?
