"Consumerism" has ZERO to do with my own comments. And I know the definition of appropriate"tools" far better than most. Technikas were pretty much standard for outdoor photography pros at one time due to their portability and dependability. My older brother used one, even from helicopters and planes using the optional rangefinder viewing system. Of course, many people needed something lighter and more compact, so back then little wooden Wista folders were quite popular too, along with similar brands. And there were all kinds of compromise models like the Toyo folder.
But I went with the Sinar system, even for decades of intense field use. I've literally walked at least 15,000 miles of steep terrain using the Sinar. And for my purposes, anything resembling a Toyo folder or Intrepid would not have been adequate. I needed the extra features, especially the ability to use long rail extensions for sake of longer lenses, without the need to default to bigger bulkier telephoto-style lenses. I also needed the ability to reconfigure the camera as needed for architectural photography, even during road travel to and from trail destinations. And better built cameras are often a bargain in the long run, especially modular systems like Sinar offers, because any affected components are easily switched out if needed, often alleviating complex pricey repairs.
Added all up in a serious backpack, the complete camera system with holders and tripod etc, etc, plus a couple weeks worth of food, high altitude camping gear, appropriate clothing and shelter, and certain mountaineering aids, and an 85 lb pack load was customary. Desert backpacking could be even heavier due to all the extra water being toted. Most mountaineers would regard that amount of weight, or even more, as simply normal on treks, and would therefore stay in shape. My attitude is, why not? It sure beats running around on a treadmill like a hamster in some stinky city gym.
But eventually, age started getting to me (I'm now nearly 74), and I bought a supplementary little 4X5 Ebony folder for sake of long-haul backpacking. But I still shoot a long-railed 4X5 Sinar Norma, or an 8X10 folder, for day hike usage, along with various MF options. AND YES, if you specialized in large highly-detailed Cibachrome prints, or now Fuji Supergloss ones, like me, every bit of extra precision counts, and adds up to the end-product quality. You CAN see the difference. Even my film holders are more precise in the case of 8X10 color film usage, and need to be.
So it's all relative to your personal requirements. If it's just for sake of relatively small magazine or book reproduction,
anything 4X5 is basically oversized overkill these days. But it was important back when editors wanted reasonably large chromes to select from right atop a light box. Yet even now, view camera movements can be a distinct advantage
in certain genre, including architecture and landscape, as well as for personal reasons. And I find them quite enjoyable to shoot, and the bigger negatives a distinct advantage in the darkroom.
