It's a "least practical vehicle ever made unless all you want to do is climb hills that go nowhere thing" thats why you don't understand. It's like a glock thing or a 1911 thing or a AR15 thing... oh wait... or an XD thing.
if you want practical, buy an XJ (regular old Cherokee). It has the same driveline as a Wrangler, will tow more, haul more, and go everywhere the wrangler will.
