Care to elaborate? I am curious how bit coin could make us less free. Anything that takes power from governments and gives it to the people makes us all more free.
Freedom is a completely abstract notion. You are technically taking power away from the government by promoting Bitcoin, however you are in turn giving power to a select handful of people who have large holdings of coins. It doesn't give the power to collective society (if anything democratically elected governments do so on the behalf of the people) but instead some individuals.
