Yep. The low hanging fruit principle in action. You can’t make anything completely secure so you put up more obstacles than your neighbor so the attackers go visit the neighbor instead.

Or in the case of targets with no neighbors like missile bases, you know approximately how long it might take an attacker to succeed, then put big guys with guns within that distance measured by time.

Unless you're a retail jewelry store. Then you are absolutely the main target in your area.
