What, is everyone told this???
I've heard from one person, who delivers oil, that our refineries are able to switch relatively easily. So, I'm unsure what the whole story is, but that's what the other comment was referring to. We definitely do refining in the US and there are several refineries near me.
But why would you do that, instead of selling the expensive oil and buying some cheap one back?
That's not to say the industry wouldn't go belly up from suddenly having a bunch of unused, expensive oil refineries, but our ability to refine US oil wouldn't be in peril from a lack of refineries.
Who would want to build a refinery when the current President has stated he wants to shut down the fossil fuel industry?
There is a big problem with banning US oil exports. Oil is priced in US dollars and this only works if the US continues to be a global political player. If the US stops exports, the price of oil in dollars will rise so much that most other countries will have no choice but to start importing from Russia again - and in a currency that is not US dollars.
Overnight, the US will experience rapid inflation due to all the printed dollars losing value for the rest of the world.

Something I didn't learn about until recently [2] was Glocalization. Wikipedia [3] says it's been around since the 80s. Perhaps now's a good time to bring it out again.

I'd also not heard of Glocalization, but it reminds me of a couple of topics that are covered in Fritjof Capra's Systems View of Life book (also a course), around emergent behaviour in complex systems and how this competes with top down command and control ideas (or in organisations as the formal and informal networks).
