People don't doomsday prep because they are currently being impacted, they prep because they are concerned that they might be impacted in the future. Now, you can paint these people as all being conspiracy theorists, but consider that they may be more like people that are concerned that the government is spying on them–which is less "I am a terrorist and this concerns me" and more of a "wait, they can do that? (Granted, they are currently only doing it to terrorists, but this still concerns me…)"
