Can't help but imagine a reality where this is widespread and people resort to installing radio reflective curtains/decorations that freely move with slight ambient air currents in an effort to scramble the reflections and make it as hard as they can to measure.

Something like a belly dance belt around the router could also work.

Other options:

  - Shielded rooms + wired networking
  - Shielded rooms + Li-Fi (wireless with light instead of radio)

Humans who want some rooms of their house to be non-transparent will need either new construction or to retrofit shielding, e.g. QuietRock drywall.
