There's a balance between everything being JIT to everyone living in a self-sufficient bunker their whole life. More agility is better for developing the economy and technology and efficiency and all sorts of good things while more preparedness is better for surviving freak events. I think we need some of both. The JITters might not survive a disaster and the survivors might not produce much value, but both keep civilization going. You see the conflict between these two directions with agricultural protectionism. Countries often pay to keep their agriculture industries local however inefficient they are. That's bad for the economy but good for resilience against disaster.
