> Ressources can be diverted at a much quicker rate with a lot more agility.

That's completely incorrect.

Covid demonstrated that. We have optimized so strongly for profit (outsource everything, just in time inventory, etc.) that we have no robustness in the face of disruption. There are now single chokepoints everywhere.

Yes, we could retool. But nobody will retool without a check from somebody. Everybody will simply hold their breath waiting for the crisis to pass. Everybody held their breath for Covid; they will absolutely do so with the knowledge that the orange clown will disappear in two years.
