I legit said
You are either insecure
or
You are a collector
Any person that buy more than 1 gun for protection is insecure, insecure in their ability to protect themselves with a single gun because of lack of skills with it
My country had a war 30 years ago and all veterans, people of 5 years of war experience only have 1 gun, there is no need for more, especially not an AR15 with all add-ons
The more guns you need for protection - the more insecure you are
