I don't know about the macro effects, but if a man can put a bacteriological reactor into his basement or garage to make the fuel for his car without a need for huge safeguards and resources, then inevitably a sample of these microorganisms will be blatantly stolen. After being cultivated in private hands, it will start to spread across the nation. Heck, a "shed still" may become a guilty little secret like in the 1920s ... 'cuz it'll all be illegal, of course. There's no way the elite will let us put grass and leaf clippings into a bioreactor and get auto fuel out of it. They've already chased people down for -- get this! -- NOT PAYING FUEL TAXES on the biofuel they made from discarded frying oil.
