It's something like 5-10 orders of magnitude cheaper to move information over fiber than it is to move the energy required to produce that same information through a [pipe/power]line.
Yes, this is weird and no, I have no idea why we do it, but it’s really weird to read “export it to east Texas” — to the extent that I had to re-parse the sentence to figure out what you meant.
Who cares if it's cheaper. It's that you're moving less of it. The more processing you can do near the source the smaller and cheaper your pipe out to the consumer can be.
Cut the tree on the hillside. Mill it in the valley. Then spend your precious boxcar volume shipping only the finished lumber out of the valley.
