I would imagine there are two reasons for one person having more than one car: fun or necessity. Fun would be a track car, off roader, etc., necessity would be a van for a big family, truck for work, electric car for driving to work.

Apply the same to guns: fun or necessity. Fun would be going out to the range and showing a target the true meaning of pain with as many different guns as you can afford, necessity would be either something like hunting or personal/home defense. I'm pretty sure I covered both of those, along with the "it's my right" non-answer. Still, that doesn't explain directly why someone would need more than one or two guns.
