All libertarian ideologies (including left and right wing anarchism) are anti-social and primitivist.
It is anti-social because it arises from a hatred of working in a large groups. It's impossible to have any sort of large-scale institution without having rules that people want to follow, and libertarian ideology arises out of people hating to have to follow rules, i.e. to be a respectable member of society, i.e. they hate society and don't want to be social. They thus desire very small institutions with limited rules and restrictions. Right-wing libertarians envision a society dominated by small private businesses while left-wing libertarians imagine a society dominated by either small worker-cooperative, communes, or some sort of community council.
Of course, everyone of all ideologies opposes submitting to hierarchies they find unjust, but hatred of submitting to hierarchies at all is just anti-social, as any society will have rules, people who write the rules, people who enforce the rules. It is necessary for any social institution to function. It is part of being an adult and learning to live in a society to learn to obey the rules, such as traffic rules. Sometimes it is annoying or inconvenient, but you do it because you are a respectable member of society and not a rebellious edgelord who makes things harder on everyone else because they don't obey basic rules.
It is primitivist because some institutions simply only work if they are very large. You cannot have something like NASA that builds rocket ships operated by five people. You are going to always need an enormous institution which will have a ton of people, a lot of different levels of command ("hierarchy"), strict rules for everyone to follow, etc. If you tried to "bust up" something like NASA or SpaceX to be small businesses they simply would lose their ability to build rocket ships at all.
Of course, anarchists don't mind, they will say, "who cares about rockets? They're not important." It reminds me of the old meme that spread around where someone asked anarchists how their tiny communes would be able to organize current massive supply chains in our modern societies and they responded by saying that the supply chain would be reduced to just people growing beans in their backyard and eating it, like a feudal peasant. They won't even defend that their system could function as well as our modern economy but just says modern marvels of human engineering don't even matter, because they are ultimately primitivists at heart.
I never understood the popularity of libertarian and anarchist beliefs in programming circles. We would never have entered the Information Age if we had an anarchism or libertarian system. No matter how much they might pretend these are the ideal systems, they don't even believe it themselves. If a libertarian has a serious medical illness, they are either going to seek medical help at a public hospital or a corporate hospital. Nobody is going to seek medical help at a "hospital small business" ran out of someone's garage. We all intuitively and implicitly understand that large swathes of economy that we all take advantage of simply cannot feasibly be ran by small organizations, but libertarians are just in denial.
