Other countries need to use trains for bulk like the US does.
Rail is just a lot more complex to plan for. You still need trucks for last-mile transport, so for the typical short haul it sometimes makes more sense to just drive to the destination directly. Then transporting by train just takes longer which isn't always acceptable. Sometimes you just need things there today/tomorrow.
So just saying its all economics when the underlying rules of the game are totally unequal is not that useful.
I can carry it on my magic carpet for even cheaper, trust me I am rich so I wouldn't lie... this time.
Trains have replaceable engines, power-lines - no battery. Trucks will not be cheaper option no matter what mumbo jumbo techno jargon you throw at it. And decades of technological optimizations. And they dont need lithium to be made and maintained.
Oh I see. You're high out of your mind. Explains your other responses.
