I know that for some, bitcoin seems to be a solution looking for a problem. But there are those for whom the idea of a currency that is disconnected from a national bank is very attractive. The idea of a "free money" (free as in freedom) has long been a dream of many anarchists/libertarians. This is not to suggest that Bitcoin is a final answer to that issue, but it has proven that the concept has a chance to succeed in the real world, and not just in the writings of idealists.
