Consolidated production has benefits like economies of scale and world peace, but at the cost of redundancy and national security. Chip production isn't actually that bad; Micron is in the US, Intel is in the US, China, Israel, Ireland, TSMC is in China and Taiwan.

What we're seeing here has nothing to do with consolidation of manufacturing; it's entirely JIT logistics. Decentralization doesn't solve that; surplus capacity and/or inventory solve that.
