Libertarians do NOT believe in anarchy. WTF? You don't even know what you're talking about and frankly, I am super sick of people like you attempting to pretend you know what a libertarian is, when you don't. And it's not just you far leftists, both far leftists and far rightists have corrupted the term, because of moronic ignorance.
Libertarianism was for hundreds of years called, "classical liberalism" however, the left then hijacked the term, and used it to describe having state controlled policies, which goes against the core principle philosophy of libertarianism, which supports decentralized power, egalitarianism (equal justice for all) and freedoms of thought, choice and non-interventionism in other people's business, including domestically and abroad.
It does not, however, support promotion of powerful private entities to violate the rights of others to be able to live freely, and not be able to have equal justice, freedom of thought, and freedom of choice. Your thought process is evidently too primitive to grasp that libertarians are against any form of having too much centralized power, regardless if this power is centralized to the government, or private sector.
We support laws that do not incentivize oppressing others, for self-gain, and instead promote fair civilized regulations that promote egalitarian opportunity for all, so it comes down to, more of a matter of your own hard work, and ambition, and choice, as opposed to not having such choice due to government or private corporate oppression.
Libertarians, and/or as previously called, "classical liberals" would include the likes of Thomas Jefferson and James Madison. They did not support anarchy. They supported a well organized democracy, that promotes democracy, and encourages the fostering of an atmosphere allowing all who want to work hard and succeed to be able to, without stifling anybody else unfairly in the process.
For example, in modern context, libertarians believe that if you want to smoke pot and not harming anybody, then fine that's your choice, if you want to have an abortion, that's your choice, and we support that people have these choices, and not being barred by criminal laws from doing these things, as long as they do not burden others with their activities. Like, for abortion, have as many as you want, but don't be taxing others to pay for your abortion, and at a certain point, the baby is a baby capable of living outside the womb, and so should have its own rights being considered, that need to be looked after. So at least for me, having rights, are not indefinite. Your "rights" end when they begin to infringe on other people's "rights." In other words, you have "rights," but you do not have "rights" to harm others. And for vices, like using some illegal drugs, that are not inherently dangerous to use, like weed, smoke as much pot as you want, but don't be committing other crimes harming people due to your personal drug use. And even more dangerous drugs, although I don't support them being legalized, and certainly do not promote drug dealers taking advantage of people because of their addictive properties, I don't necessarily believe we should criminalize those that are using them, because most of the time, they're just sick, and its not something that should go through the courts. Those purposefully harming others trying to get people hooked, should be prosecuted, because they are oppressing people through personal greed, and directly harming others. But if just addicted, and using, that's something they need to address with medical intervention, not by the government as a punitive matter. So deregulation is not the same as anarchy, because we do support regulations when the said activity oppresses others unfairly, and especially when it then infringes on other people's freedoms of choice not to have to pay for your abortion, or be hit by a car, because somebody ran a red light, driving high on pot, etc. Make sense? Because if this does not make sense to you, then you obviously don't know what you're talking about, so need to stop acting like you know anything about it.
I'm a Libertarian for the reasons I specifically described
