Unfortunately lightning is not that much energy. It is high power but not high energy. Furthermore a lightning strike is a very rare event. It might happen once every ten years - a number that varies significantly with other factors such as geology.
So we typically spend about $1 per protected appliance for best protection of everything from direct lightning strikes and other sources of surges.
