No matter the logic and diligence employed in the determinations, the goal for almost everyone is personal security. Having enough food for the day. Being relatively safe at home. Etc. The basic goal in all of economics is trying satisfy unlimited wants and needs with limited resources.
Some of us will feel safer if we a weapon. Some will feel safer if we have a security system. Some of us will feel safer if no one else has weapons. 
Some of us will feel safer if we strengthen our perimeters with Foo gas. 
Trust: I trust a few people, mostly immediate family and close blood relations. In God we trust, everyone else keep your hands where I can see them.
And my fundamental most important from among the USMC Rules for Gun Fighting: Your number one Option for Personal Security is a lifelong commitment to avoidance, deterrence, and de-escalation.
Have a great weekend.
