Re your third point - this is one of the main critiques of Capitalism, the reckless disregard for the bounds of growth.

In an ideal world, yes, we should build our own trains, but personally I think that’s putting the cart before the horse. Let’s get at least one portion of the track laid and functional before we start imposing more requirements. We can’t support an American train building industry without tracks to put those trains. Any investment in infrastructure increases the likelihood that others build on that infrastructure.

Could you link those? I’d like to read them!

I mean, will it happen eventually? Yeah, no doubt. But could it take 15 years? Also yes…

Great if it happens, but not holding my breath.
