...unless I have misunderstood your arguments, you have been suggesting that if a universal constant, such as alpha, is contingent then it could possibly have taken many different values.
I don't recall mentioning alpha up until this last post, but what I have argued is if the collective properties of the Universe were contingent then the Universe could have taken on many different (e.g., an infinite number of) properties.

Therefore the only explanation that circumvents a fantastic dependence on chance would be a higher intelligence guiding the values of the universal constants. Has this not been your argument?
I think there's a major difference between this anthropic argument for
this universe being life-supporting compared to my argument for the Universe having enough potential complexity to bring about significant structure. In the first argument we cannot be sure if string theory, quantum loop gravity, eternal inflation, or some other known or unknown hypothesis is responsible for this universe having the properties that it has. Therefore, this argument reduces to my argument which is that the Universe is either contingent or necessary. I don't spend much time trying to defend the fine structured constant as being constant since I think this is a scientific question. Don't get me wrong, there is significance in the fact that the universe's constants are fine-tuned, but only in so much as that this demands a Universe with significantly higher potential complexity. It's this potential complexity that the atheist often assigns to contingency, and that's where I see atheism unable to do so without relying excessively on luck. I argue that a one-time property set of the Universe wouldn't be so lucky.
