Even if this were true (and it seems more likely that the
author was either misinformed, referring to a specific
military-controlled insulation, or extrapolating from some
specific type of structure to structures in general),
I'd think going along with the premise of it's easier to get
forgiveness than permission could innocently achieve
the same goal.

Should you eventually find yourself standing before a
judge, you can tell the court,
   "Your honour, it's NOT tempest shielding. I just live
   inside a giant microwave oven."
