ELI5: What exactly do people who call themselves Libertarians believe?

My understanding of it is that people should be allowed to do whatever they want assuming that it harms nobody else. But where is the line drawn? I mean, driving a car when drunk can harm somebody else, but so can just driving a car at all and having an accident. Most things in life have an inherent danger that we attempt to regulate and minimise with laws. So to what extent do Libertarians want any regulation at all, and is it just immediate harm, or do they take societal consequences into account, considering they do live in a society after all.

Also, I realise there are degrees to this amongst different people who claim to be Libertarian, but what is the overall philosophy? And what about the fact that famous Libertarians also happen to be quite wealthy and don't require government assistance.

Your first sentence describes a libertarian manifesto. Some libertarians take it a step further to the nonaggression principle. Although that is more of a individual philosophy than a political ideology. 

There's three natural rights, property, body, and mind. These can be thought of as your freedom in the past present and future. Property is the fruits of your labor. Body is your right to liberty. Mind is your right to speech and thought. Only when one of these three natural rights are infringed should anyone have a right to prosecute anyone.

Yelling fire in a crowded theatre could threaten lives therefor it should be illegal to do so.

The income tax is involuntary, you cannot owners without paying it. Therefor it should be abolished. Whereas the gas tax and the property tax, are taxes which you voluntarily pay by using such goods. You don't have a natural right to land or gas. There was no income tax until 1913, and we were fine because we did not have a standing army. We relied on a draft in case of just defense of our soil. Which has only occurred once in us history at pearl harbor which was provoked by rude "diplomacy" to the honourous Japanese. 



If a pregnant mothers life is in danger due to her pregnancy, she has a natural right to abort.
