Well, I don't agree with that community is the issue. Besides, I agree that it will take risks for most of the people. And seemingly, you need at least some of the USD( or other currencies) of bitcoins to advertise on official website like localbitcoins, so it is for the people that could take this risks. Even though, I personally believe freedom of financial will eventually come, whether it will through the cryptocurrencies or not. I have to say that I have some doubts on cryptocurrencies.
