Exactly! And statistically, this is more probable, as many more households are "close" to each strike, in which only one household takes the direct hit....from a close, but not direct hit.
People would like to make fun of our old nuclear bomb drills in school, when we'd climb under our desks, saying it's a completely futile exercise. These people don't understand that you're many times more likely to be "near enough" any such event to experience things like windows blowing out or roof tiles falling onto occupants, than to ever be the one building unlucky enough to experience a direct hit. The same logic applies to lightening strikes, in which a surge supressor might save you from many damaging events happening near your home, if not the rare direct hit.
Good point! Even in the industrial electronics where I work, surge arrestors often look like someone placed a grenade inside the housing and set it off, after they've done their job. These things are all made from fire-resistant or self-extinguishing materials, but the walls to which they're attached or the carpet upon which they're set, may not be....preferably on the outside wall of the house.
One thing I wonder is how many damaged or totally-defeated surge surpressor systems are out there today, in the consumer world? What fraction of us are running on equipment that's too damaged to do it's job anymore, without even realizing it? Some have indicators to (possibly) tell you when the internal components have been badly degraded by past events, but I suspect most do not, and those that do may not indicate all failure types.
