While I understand your frustration, government is not the answer. I have a million bullet points and examples over the past 100 years that would solidify my position, but I'd have to censor myself for talking politics. 
In short, while FICO is the best predictor of credit behavior out there (otherwise lenders would be using something else), regulating scores to ONE system (e.g. FICO) isn't the answer. If, down the road, FICO screws up and introduces a failed product to lenders, the last thing we would want is government telling lenders they have to keep using that system. The market needs to remain open as it is now (e.g. Vantage, PLUS, etc.) to let lenders decide what score is the best to use. It just happens that all other scores out there are so poorly designed and implemented that lenders won't touch them at all. One day, I predict, a score will be created that trumps and rivals FICO. Fair Isaac has such a long track record of being on target that there is no competition currently.
One example I can think of is Microsoft. Windows was it in the early 90s. Apple stunk (used an old Mac and it always crashed). If we insisted that government step in and demand that only Microsoft be used, then there would be no Apple today and all of our PC computers would be crashing (like my IE does every umpteen minutes).

I agree with Ilecs, the market will do a MUCH better job of determining what works best than the gov'mint ever would! Although, your example makes me cringe. If there were no Apple, I wouldn't have wasted so much $$ buying, then ditching, an iPhone!! 
lol
I don't think it would be a bad idea though if a minimal set of guidelines were set, one being any product (scores, be they traditional, CC enhanced, auto enhanced, etc...) that are available to lenders should be made available to the consumer (for a nominal fee, of course).
