you can buy prepared metal, wires, microchips, buttons and other needed materials easily, down to plastic beads you can put in a mold (or more likely, just 3d print these days),
Do you think those appear out of thin air? Because that was my whole damn point. Those prepared items come from other parts of the world. You can’t manufacture all of them in Europe and if you tried, it would take a hell of a lot more than five years and drive prices up ridiculously.
I’m not sure why you think I’m talking about final assembly when I’ve made it clear multiple times that I’m talking about all the steps before final assembly, many of which require global shipping.
