I say yes, however it is limited (for now [my opinion]).
I think of currency as freedom for a lot of things.
It is freedom from starving. Give me some food and I' give you money.
It is freedom from going to jail (in the U.S. at least and in a lot of cases). My (highly paid) lawyer says that I did not do this crime and can prove it.
BitCoin doesn't offer this yet (or not as easy). You would have to convert your BTCs first.
BTC is gaining greater acceptance. With more acceptance, comes more freedom (or easier freedom).
Keep in mind that (in the U.S. at least) cash doesn't offer freedom at all times. I have seen signs (I haven't in awhile) saying that they do not accept cash (Checks or Money Orders Only).
I assume this is because of all the movies I have seen (maybe you have), I never saw this:
Masked person holds a gun to a clerk and demands, "Give me all of your checks and money orders!!!"
Grated they could use ID theif to cash them (and have the police waiting for them).
