Normally I also look to Dogbert for occasional bits of lighthearted wisdom, but in this case I'm not so sure that his model applies to the matter at hand.
When he says "Actually, developing countries would buy the oil that you saved, thus adequately funding those same terrorists", this suggests that the USA is somehow preventing them from buying more oil from terrorist supporting nations at the moment, and if the USA were to buy less oil from the terror nations then there would be more available for 'developing' nations to buy. They would then buy this oil that the USA would have bought, making the matter of sourcing irrelevant.
This presupposes that there is a finite pool of oil (pardon the pun) that everyone is fighting for, and if one buyer buys less, that means there's more for everyone else, which they would then immediately buy because they aren't buying as much as they want to at the moment.
I would suggest that oil importing nations are buying what they need and what they can afford, and what they buy is not necessarily limited by the purchases of other buyers or the available physical supply....there's plenty to go around, the main limiting factor not being available supply but the market price, which is set in an intentional and artificial way by the OPEC sheikhs who manipulate production levels to keep costs high.
If the claims made by this group of Florida investors is true and the entire production and distribution pathway of their product circumvents terrorist-supporting nations, then it sounds to me like it may be a positive thing. Nobody is suggesting that this one small station is going to be the ultimate solution to all energy worries, but according to Petronski's posts this is already a tried and true business model of Kwik-fill.
I will be interested in seeing an analysis of this venture by economists at the WSJ or the FT when this business gets up and running and can be analyzed properly.
It would be cost prohibitive to build a closed loop production, transportation, refinement and distribution network. Unless of course you are willing to pay $50.00 a gallon for regular unleaded.
