Honestly? The world's chipmaking should be more decentralized simply from a national security perspective. One needs to only look at the effects of sanctions on russia, once one of the world's preeminent superpowers, now lacks access to chips to such a degree that they're repurposing hugely expensive surface to air (s3-400) missiles for ground attack and relying on iranian drones for precision attacks.

The fact that china could reduce 63% of the world's chip making capacity to rubble at a whim is a strategic threat to the global economy. This is one area where we could absolutely use some redundant supply, even at the cost of taxpayer dollars.
