What does "cold rolled 30 times" mean? Do you know? See, I do, because I have a mechanical engineering degree and a background machining and metal work. I don't think you do, because if you googled it you'd know that it doesn't do anything to affect the finish of steel whatsoever. Every stainless panel you've ever seen on every dishwasher and every refrigerator has been cold rolled. The way you make cold-rolled steel not show every blemish is by embossing so that you don't show imperfections, either small- or large-scale. This is why you see quilted stainless on food trucks. Here's a question for you: which has flatter panels, the Ford Model T or the Ford Model A? If flat panels were stronger, why did the whole world evolve from flat panels to shaped ones? What, in fact, is the function of shaping? Is it to add needless work and flash to a product and therefore charge more money, or is it to increase the structural integrity of the component? Are aluminum cans curved or straight? What about Winnebagos? Does the shaping of metal increase its resistance to flex by providing rigid structure outside the plane of force? Or has this all been a conspiracy since the Bessemer process to rip the world off? See, I know the answers to these questions and you could too, with a bare modicum of research. The automotive press has been making much of the fact that the thing's a unibody; okay, so was the Subaru Brat. So's the Honda Ridgeline. So was the VW Beetle. The way you used to get the strength out of a monocoque structure was by welding it; nowadays you might bond it instead. Either way, I don't have to "imagine" what replacing them would be like; I've done unibody work and it's destructive and time consuming. So you can be as flippant as you want. But just because you don't know the answer to something doesn't mean nobody knows the answer to something.
