The problem isn’t that it can’t be done, it’s that the manufacturing cost vs. labor cost in the US stops it from making economic sense. They do repair and reuse electronics in places like China (that’s where those modified GPUs with extra RAM and cheap desktop motherboards with old Xeon CPUs on them you find on EBay and Aliexpress come from, for example), but that’s because the technicians doing the work get paid a lot less than skilled people would be willing to accept here.

Also, much less labor law burden. No pesky ppe required while breathing toxic fumes!
