I have yet to see someone screaming on the evils of "equal outcomes" come out and admit that, in society, individuals who could afford certain things would not choose to live below a certain standard of life, like drinking toxic water that makes them sick. The glorification of "choice" above about everything else, ends up having immense rationalization for depravity people live in that it is their fault, or is chalk off along the lines of "you have to break few eggs". And, without resources, there is few liberties, only enslavement to circumstance.
I could also say there is a parasitic nature to Libertarianism. Individuals believe everything is in and of themselves, and they don't get any benefit from anywhere but themselves. And then they oppose taxes and whatnot. The will end up scheming and plotting for their own end, and presume that what they do only has an impact on themselves. In short, it is the mindset of a parasite, with delusions that everything here comes about because choice, in and of itself, produces magical results and abundance for everyone. And of course, the ONLY evil that comes about is from governments with their bullying.
Want to know what can cause the next Great War? Well, elites who fail to show any concern for the rest of humanity, and have pockets of depravity, and individuals who then go, "enough is enough". But, odds are it will end up being an escalation of a single incident and individuals not backing down.
