I think this topic realistically is kind of absurd. Under this logic, you never need an iPhone, iPad, most people don't need computers or aquariums, etc. The list could go on and on. Jeeps are just like anything else. If you do what intrigues you, within your budget, and hurting no one else than that's what you do. This post intention is almost like saying well since I got aftermarket wheels with my tires i'm buying stuff I don't need. Well, I suppose thanks for pointing out the obvious but it's what I wanted.
And honestly, a jeep is kind of a fashion statement. For every 100 jeeps on the road 1 of them is probably the only likely one to every see anything more than the oddball dirt lane. This isn't true to the population on this forum i'd like to think, but nevertheless without those other 99 people jeep wouldn't keep producing the vehicle for the small community that represents us.
I tinker with my jeep/cars/bikes/whatever else because it's my passion. Building something from the ground up, regardless of everything is "for function", is what I enjoy doing with my spare time, give me a wrench and a new part and I'm like a fat kid in a candy shop.
