> We could probably slash gas prices by banning oil exports, thus removing domestic oil supply from global market pricing (barring smuggling).

To my understanding, you couldn't do this, no. The US is a net oil exporter, but many of its refineries are tuned for processing oil with a chemical composition that isn't found in the US, or not found in sufficient quantity. So the US has to both import and export oil, it can't just replace imports with exports.
