You're missing a major element: the relative measurements of your wifi signal...a.k.a. radar inside your home, visible to people outside your home.[1] Your wireless router sends out a constant signal . That signal bounces off stuff, and can be measured in real time. Once a 3rd party has a calibrated measurement of your wifi signal, they can scan it and make relative measurements in real time. They can reconstruct what's going on in the room by reconstructing the triangulation of how the signal is changing. They've been able to fine-tune it enough to see a person breathing, or see their heart beating. As this technology matures, I believe this will be the next-level of major privacy concerns.
