I think it is wise to be concerned about ones freedom - I think it is possible that Nakomoto anticipated everything - I am not sure what you mean about my "impact on it" - are you saying that I have created more "security" for the network than I need to worry about? I think that is would be an interesting thought and while I would agree that every user/miner/node "helps" grow the network....I am not sure that they all are doing so with the idea of "helping" the network....

While some governments of the world might be? I am certain that there are others who are trying to co-opt it somehow, someway....This network ends their ability to fund themselves....
