Well, Jeep Wranglers are certainly a unique offering. And "true" Wranglers--not the "bus Jeeps" as my brother calls them, only offer seating for 4 and have practically no cargo space.
But the truth is that people who buy Jeep Wranglers are motivated by something other than practicality. For many out there... It's a Jeep thing; they wouldn't understand.
On an objective level, they're pretty terrible vehicles as daily drivers. They're heavy, bumpy, handle terribly, get horrible gas mileage, don't offer anywhere near the creature comforts of other vehicles, and they're notoriously unreliable. Objectively... They're shit. And yes... I own one. It's a Jeep thing. 
But I get it. If you're arguing the contrarian play, the Jeep Wrangler suffices.
I'm just pointing out that there can be-- and are-- design choices that are made, that are unrelated to aerodymanics. So the stereotypical humpy shape of the modern small SUV or crossover isn't necessary. It's a choice.
If you want to say that modern 4-door Wranglers aren't "real Jeeps" then that's fine, although the proper derogatory term from 2-door Jeepers is "minivan" rather than "bus." Take it from me, I've heard it plenty from "real" Jeepers whilst out on the trail.

But when you argue that, you're actually reinforcing my point. The modern 4-door Jeep isn't the same as your vintage 2-door model. They're not even the same as the modern 2-door models. When antagonists refer to them as "mall crawlers" they're actually just underscoring the point I've already made. These vehicles aren't being used for offroad adventures, they're being used as small SUVs for around-town errands. Small SUVs that look way cooler than the alternatives.
And yes, even a 4-door model of Jeep Wrangler is pretty compact in width and length. At 188.4" long it's less than an inch longer than an Acura RDX. And it's almost an inch narrower, 73.9 for the Jeep, 74.8 for the RDX. So, very comparable in length and width. And despite that, behind the second row seats the Jeep has 31.7 cubic feet of storage, versus the 29.5 cubic feet offered by the Acura RDX.
And another point, the 4-door version dramatically outsells the 2-door version. About 85% to 15%. And it's true that the shorter wheelbase of a 2-door Jeep is an advantage when performing a variety of offroad tasks, and especially rock-crawling. But, as I've stated, the majority of 4-door owners aren't buying them for offroad adventuring.
And finally, you clearly haven't driven a modern late-model Jeep Wrangler. I have, I drove a brand new one a couple months ago when a friend bought one. They're pretty nice. Not to the level of an Acura RDX I'm sure, but they're a MUCH different driving experience, than the one you currently own (and the almost 10-year-old one I currently own, as well). They have all sorts of bells and whistles now. It still has a solid font axle rather than IFS, and it's never going to be a luxury cruiser, but it's also substantially different than it used to be.
The point of all of that being, I classify them as a reasonable competitor or substitute for the humpy crossovers that all look alike, and aesthetics are potentially a deciding factor in the people that choose them over the alternatives.
