Citing the black market is not the best evidence for utility. Global remittances is clearly a market that overlaps very well with Bitcoin and I would argue that Bitcoin can achieve the same features at lower cost. However the skeptics are correct that this particular use can be satisfied by very many other cryptocoins, so it's not unique to Bitcoin.
