The question isn't "Is BitCoin's value non-zero?" As a general critic, I freely say up front, yes, it's interesting and has some non-zero value. I won't even say I'm "admitting" it, because it was never my contention otherwise. But merely establishing that there is some aspect with a non-zero value isn't interesting. The question is, do the positives outweigh the negatives, and if so, do they outweigh them enough to fulfill the stated goals?

You can make anything look great by considering only the positives, you can make anything look terrible by only considering the negatives. The question at hand is about the balance, not whether BitCoin has any positives at all.
