A modern analogy compares castle defenses with layers of household security, from guarded compounds to alarms, cameras, locks, deadbolts, and doorbells. The useful question is whether Bodiam's owner bought a sensible level of protection for his wealth, status, and risks. A lower-ranking noble had to cut his cloth according to both means and need, much as households choose different security systems today. The comparison also points to a persistent inequality: people with the greatest need for protection may have the least money available to buy it.
