Final answer:
Castle Rock is considered an ideal home for savages due to its fortified and secure location, much like historical and prehistoric sites chosen for their natural defensible features.
Step-by-step explanation:
Castle Rock is an ideal home for savages because it is fortified and secure. Throughout history, defensible sites have been crucial for protection and survival. For instance, major cities in Europe were often located in places where natural fortifications, such as islands or hilltops, provided security against outside groups during the Medieval Period. The European feudal system even structured its social order around the concept of lords providing protection in exchange for services.
Similarly, settlements like San Francisco were chosen for their defensibility features, like being on a peninsula which offered military advantages against invaders. Additionally, prehistoric indigenous peoples often lived in rock outcrops or sheltered areas, using both natural structures like caves and cliff alcoves for protection against predators and inclement weather conditions.
