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.
No. The rich do not have the power to demand we act in certain ways, lest we be caged or murdered. Only the insane belief in the authority of governments leads to that power.
