Resisting the urge to be snarky, self defense is a legitimate answer. You may not live somewhere where it's common (or you may not frequently feel unsafe) but wanting the ability to have a weapon to defend yourself (or more commonly to show that you have the ability to defend yourself) from any assailant is a very real thing for people both in the US and around the world.
There are plenty of women with restraining orders against men who would do them harm who would very much suffer consequences, and be made much more afraid for their safety, if it weren't for "guns that shoot people".
