Libertarianism is really just another form of feudalism in the end.Officially a libertarian hell hole
The biggest non-rich supporters don't even realize this because the propaganda to sell it to the masses is effective as anything but the above. The dream is that lack of government regulations and lack of government, or in the most extreme no government, is needed because "freedom" and unrestrained capitalist concepts will be enough to bring order to society and fairness for all.

Reality is that society is always going to be composed of individuals who will aim for maximum amount of power allowed. A lot of time this is tied to who controls the most resources. No restrictions on this will lead to a small class of nobility, lords, kings to hoard every resource that exists while the average person loses more and more until they are simply labor for the upper classes and own nothing. Libertarianism advocates for exploiters and resource hoarders to go to the extremes without limits. This will be the inevitable result.
This is why the wealthiest individuals in society love it. All these PoS tech investor billionaires are on that anarcho-libertarianism wave because they stand to gain the most under a system. Those who aren't a part of that class don't know they are signing on for their own disenfrancisment.
It's better to have a government who controls the ultra capitalist class. At the very least it's answerable to people through voting and action. You can't vote out a billionaire oligarch.
