What good is protecting your brain only? You need to wear it everywhere. They make Faraday suits that look like hazmat suits. The bonus of wearing that everywhere is that you're completely anonymous since no one can tell who you are underneath (the only downside being that you're now the guy wearing the Faraday suit everywhere).
Also line your walls with tin foil. Or at least turn your exterior walls into a Faraday cage and put up steel grates over your windows. You won't be able to steal your neighbor's wifi signal, but at least your neighbors won't be able to throw a brick through your window and steal your stuff either.
Stucco is basically concrete troweled onto steel mesh. If you pay some attention to making sure each piece of steel mesh is electrically connected to the adjoining pieces, and grounded, and used aluminum screen over the windows (or maybe used metallic film coatings on the windows), steel doors, and either installed conductive screen over the attic floor or used steel roofing (the good stuff isn't cheap, but will pretty much last forever, never need to re-roof again), you'd probably have a pretty good Faraday cage.
Maybe add a whole-house low-pass filter where the power comes in. You could get one that provided whole-house surge protection at the same time.
Wouldn't be easy to retrofit, but if you were building, or doing major rehab, it probably wouldn't add much cost.
