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.
You got a point there. If there's no government in a country, there will be crimes everywhere. It is going to be scary to live in a country like that. That can also happen to bitcoin. Before when bitcoin was new, so many hacks and scams that happened but the moment bitcoin was now regulated, many criminals have got caught and the cyber crimes have now lessen because the criminals also knew that they are not safe anymore if they do crimes related to bitcoin.
Some people are waiting for the bitcoin to be recognized by the government before they get convinced to get involved in it. Government really plays a big role in the bitcoin adoption.
