It seems like you're conflating government with social organization. Think about how a society could have social organizations like welfare, social security, medical treatment, mental health care, and all the other wonderful aspects of an organized society without combining that with the use of force to make people contribute to specific organizations or ways of living. That's what Libertarianism is in my mind. It's not about reducing the scope of social organization, it's about divorcing that social organization from government and minimizing the responsibilities of government. When government gets large enough it A) ceases to act in the best interests of its citizens and B) starts to legitimize the use of force against its citizens. Take a look at how our police forces are militarizing and our elected representatives are ignoring us for a pretty concrete example. The nice thing about small decentralized government is that even when it ceases to be of and for the people it can be taken down relatively quickly and painlessly. The problem with the Libertarian approach is that it's genuinely hard to get people to agree with each other about whether a social endeavor is worth their time, and in the mean time real people are affected by whatever the societal ill is. That's something that we have to be willing to accept if we want to reduce the scope of government. We also have to be willing to accept that there are different ways of living that we might not agree with. And we have to be willing to help people who want to be in our society to join our society. The real problem is that no matter what our society looks like, it's hard to get people to look past their knee-jerk reactions and try to be tolerant and understanding of others' ignorance. And that cuts both ways.
