It simply isn't practical. We have technology to build devices with micron tolerances, but they cost millions of dollars. Sure, you could build a device to sew a pair of jeans with millimeter tolerances, but you'd have to be so precise that you'd have to charge thousands for a single pair. That's not even looking at the material itself. Different fabrics can have different tolerances for stretching in all directions. It is a big tradeoff between accuracy and cost. If you want to have the measurements be hyper-accurate, be prepared to spend a ton.
