Libertarianism may be the political philosophy in fashion amongst my generation. However, I am 99.999% positive that it is not an adequate solution to our social, economic, and environmental problems in the present or in the near to distant future.
Yes, there are some things that government cannot and ought not do for its own sake, because it harms society and, thus, harms itself in the process. Government is also liable to make mistakes from time to time because it is an organization of humans and organizations of humans are only as good as its occupants are able to work together. This does not mean, however, that government is not an essential component in the production of a healthful, healthy, and functional society within the context of our environment. Sometimes it is necessary to legislate and enforce against certain actions, behaviors, and practices that cause harm to the people who live in society and to the environment in which we all live. Thank goodness we have an institution within our society to do this, because without it, we would have to resort to vigilante violence or the slow and improbably functional practice of the market forces to work out our problems quickly and effectively in favor of the public. This would then shorten everyone's perspective and priorities to the shortest term possible, disrupt business connections and connectivity, and ultimately destroy our environment and our society for the sake of Libertarian's beliefs and abstract ideological goals which wouldn't be realized in the chaos that would ensue from their policies, beliefs, perspectives, and actions. How dare they jeopardize our well being for the sake of their beliefs and personal preferences for unnatural chaos (which they've more likely than not, never actually experienced before in their lifetimes).
Human society requires a certain amount of order in order to survive and reach optimal states. It's incredibly childish for people to think that they can go without having a benevolent, effective, and empirically grounded organization assisting with sifting through the negative aspects of society and providing some kind of vision for society's function (based on how a society would ordinarily self organize and function from the beginning). The key to government is dialogue with the public and accountability to the public and its well being, and dialogue amongst government on the horizontal and vertical levels of government. It's a team collaborative effort to produce well being for everyone, not just the few who have the most amount of wealth in a society, if the government and its members are interested in surviving. That's something that Libertarian philosophy does not and will not take into account, thus, rendering it a nice sounding, but ultimately sub-optimal system of social function and organization.
Sadly, I think that we're ultimately going to go through a phase of Libertarianism, thanks to the failures of both the existing parties in the United States to organize government effectively for the public over the private elites. It is presenting itself as the third way, and people are going to go over to that third way, regardless of its actual merits, if it speaks to them in such away that sounds pleasant to them. Ultimately, I can only hope that the public realizes that Libertarianism is not the way to go for its own sake and benefit. I cannot force society to take in my conception of empirically grounded social-ism anymore than the Libertarians can make a functional, healthy, stable, happy, and livable society with their perspectives, attitudes, and beliefs. Thus we must all suffer, because of the karmic actions of the general public (myself included, because I do not want to see society operating at sub-optimal levels). It takes a little bit of government action and proactive dialogue in order to make a society tick, from the perspective of the government's well being. It's sad, but the legitimacy of the government ultimately lies with the public. Sometimes the public is wrong when it comes to making big, complicated choices for itself. Those of us who would hope for the best for society by listening to what it wants and needs rather than imposing a regimen on them without consideration of a diagnosis will simply have to wait, hope, and organize, if possible, for the sake of society and the world in which we live in.
Think about it.
