The ones who are telling you to rid of the government are people who wish to control you.
Though bitcoin is decentralized, we can never get rid of the government as they are the ones who maintain the law and order of the world, without them, the decentralized world will be in chaos. Bitcoin is a currency, it does not have the power to control us, we are the ones who supports and give life to bitcoin, but without the support of the government, cryptocurrency will never be adopted and probably will not survive in the long run.
The network can't be interrupted which makes bitcoin unstoppable by any government. Through regulation and strict law the usage can be restricted, but the same doesn't help in keeping people from using it. There is always some loop holes and common people make the use of it.
Over the last year the cryptocurrency adoption rate is quite high. People will find it an opportunity to have financial freedom. There is nothing to think about the potential, because bitcoin have already proven it to the world.
