I guess no one "needs" a steak either, since you can get your protein from soy products, but I think I would rather starve first.It wasn't put forth as a jest.
Nobody needs a bolt action sniper rifle.
How can you argue that?
See how things go when people justify possession by 'need'?
I am not arguing that I need a sniper rifle, but since they are accurate and I like to hit steel and rocks and other targets a long way off, I just want one.
