To your point - we do have some chokepoints in supply chains here and there but I often wonder how much of that is due to the learning curve. As in, things are centralized because just how we as a civilization learned to build things in our particular historical context - if the context changes and the knowledge and resources are there to rebuild in a different way, we can.

Relatedly - a lot of things seem intrinsically capital intensive, but how much of that is due to the fact that we had large pools of capital when we learned to do those things?
