Before we continue, I would like to be clear that the two belief structures examined below are the not only ways that people become libertarians. I'm not even sure that they're the most common. But they are the most interesting to me right now, so here we are.
First, there are those who become libertarians because they believe it is the right ideology. By right I do not mean morally right, so much as pragmatically best. Morality is often intertwined, though, especially from a rule-utilitarian standpoint. This sort of libertarian believes capitalism is the best economic system, democracy is the best form of government yet devisedimplemented, and the Constitution works pretty well.
Second, there are those who become libertarians because they don't believe they know how to run other people's lives. They see libertarianism as the only option for not forcing a belief system on others. These sorts tend to be divided on capitalism and democracy and definitely biased toward anti-constitution anarchism.
I came to libertarianism from neoconservatism through the first camp. I was very confident in capitalism, but didn't find social conservatism (or religion in general) very appealing. Moral behavior without government enforcement was interesting but didn't seem very viable. It wasn't until discovering Objectivism that the possibility of morality in a godless universe was really presented to me in full, and thus becoming a libertarian became much easier.
Since that time, I've spent some time in that other camp, especially when those ideas are popular (for example, Gary Johnson's campaign in 2012 relied heavily on that rhetoric), though it wasn't a comfortable experience. In part, those arguments lack rigor. It's easy to say "I don't know how to run your life better than you do", but for a significant segment of the population, having someone else take over would be a vast improvement, from reduced responsibility/stress levels if nothing else.
A better argument would be to point out that, in the space of possible policies, most will do more harm than good. However, committing to the position of not-knowing is not a good move in the greater debate. Libertarians have long been able to switch between the two mindsets depending on what the conversation demanded. This is a pretty basic motte-and-bailey strategy, which the more rational subsections of the movement should attempt to avoid.
In all fairness, there's a possible middle ground between these two positions. The argument goes something like this:
Good luck winning debates with that approach. To argue for hands-off economic policies, you should have evidence (or at least theory) that indicates doing so produces better outcomes. That's a bit more difficult and, I believe, the more rational thing to do.

The space of possible policies is incredibly huge, and it's very difficult to determine which are superior. This is true whether we're talking about macroeconomics or how to decorate your bedroom. Because this is so, we think people should be left to their own devices so that they can experiment with policies at their own discretion until they feel satisfied. However, I have opinions about what the optimal policies are.The discerning reader will notice a problem here. Laissez-faire in the realm of personal lives is very different from laissez-faire in the realm of, say, fiscal policy. If you do a terrible job decorating your bedroom, that affects you and maybe your immediate family. If the economy crashes, that affects millions of people, sometimes quite significantly.
Good luck winning debates with that approach. To argue for hands-off economic policies, you should have evidence (or at least theory) that indicates doing so produces better outcomes. That's a bit more difficult and, I believe, the more rational thing to do.
