Micro, was not disagreeing with your post.
The conditions that you lay out have existed for many years - well before the jihadii usurper stealing/buying the office he occupies.

Not only do boutique blends, differing for every block in a city and time of day, drive up the cost due to loss of economics of scale - they destroy the fungible nature of gasoline, making it impossible to 'trade' from areas of high supply to those of low supply. Competition is ELIMINATED - the only real 'cost control' factor in any legitimate economy.
There is another issue also that adds anywhere from 20 cents to 50 cents per gallon (possibly more) - and that is the elimination of MTBE from being the most cost effective (AND SAFE) oxygenate additive for blending.
