I was trying to be a bit dramatic there...

Sure, it affects everything and given the complex interconnections and dependencies within production chains / networks, the cause-and-effect relationships are hard to understand and cause for concern. But given how complex and decentralized things are, I am still amazed we haven't seen worse effects (yet). I doubt that spare capacity in logistics alone would make a huge difference, because you'd also need spare parts, materials and manufacturing capacity, all of which are part of the same network.
