My first reaction also but think about it. An airbrush isn’t an airbrush but a pneumatic system. An electronic toy isn’t a toy but an electronic system. At a large enough scale and over a long enough time frame.. lots of things are strategically important when you’re talking about the basic ability to manufacture stuff independently
Right? Its like a ballpoint pen. A basic commodity. But there's a lot of challenge in manufacturing the tiny balls and the tips to such a high amount of precision to mass produce quality ones cheaply.
Just looking at the diagram of the airbrush, there's a little bit of complexity there in machining all of that good, quickly, and at scale. Lots of little parts to control it which to work well need to have high quality machining.
