Most neo reactionaries are ex libertarians, or ex anarchists.
Indeed, if you are a feudalist you are not even an ex anarchist. You are an anarcho capitalist who doubts that most people should be allowed authority in the anarcho capitalist system of enforcement and justice, or are likely to receive a substantial voice.
“I pencil” is a famous criticism of socialism, which shows how difficult it is to centrally plan a pencil.
The problem is made much easier by good fences – and the occasional armed rentacop and fierce guard dog keeping an eye on those fences.
The socialist looks at those fences and says “the fences are unproductive, and the guard dogs are not only unproductive but costly and dangerous. They also look unfriendly and uncomradely, they divide us. Let us therefore abolish them”
And then the socialist, attempting to produce a pencil, produces instead many miles of red tape and a severe pencil shortage, frequently followed by a gulag full of “wreckers” that he blames for the pencil shortage.
The fences and the dogs serve a purpose, that purpose being to subdivide big problems into subproblems small enough to be manageable. Central regulation, on the other hand, bureaucrats claiming the power to meddle in what goes on behind fences, turns many small tractable problems into one gigantic mess.
Libertarianism works provided you have fences, and often enough you also need rentacops and vicious junk yard dogs to make libertarianism work. And it is the only thing that does work to make a modern economy function – apart from terror and mass murder, and terror and mass murder does not work nearly as well as libertarianism and fences.
Libertarianism does not work where you do not have fences. Public transport in America fails because of blacks. To make it work again, you really are going to have to send blacks to the back of the bus. Whites just will not ride buses with significant black ridership, for excellent and glaringly obvious reasons that no one dares mention. You wanted integrated buses, got buses with no white ridership.
Similarly “integration” was in practice black workers in Detroit riding on the backs of white workers in Detroit, shortly followed by the dispossession and ethnic cleansing of whites in the inner city and Detroit. Detroit’s car industry failed because they were forced to treat productive and unproductive workers alike and were forced to hire unproductive workers. Ayn Rand depicts this, without, however, mentioning the overwhelmingly predominant race of the unproductive workers. When Detroit was thriving, she accurately predicted its future as a desolate ruin, abandoned by all civilized people.
If you have blacks and whites in the same classroom, the blacks are very much louder, take up more space, and are dangerous and threatening, disrupting education and forcing the white kids into submissive roles.
Further, the kind of discipline required to make it possible for blacks to learn in a classroom is a lot more severe than the kind of discipline required to make it possible for whites to learn in a classroom. Few blacks are capable of learning without being whipped. Successful black schools are harsh, and the harsher they are the more successful.
And of course, at a certain age, the blacks are into, or have completed puberty, and the black pupils are man sized and able to beat up the teacher, while the whites have not begun puberty, or have scarcely begun it, and are still child sized and still behave like children.
And if you have twelve year old white boys and twelve year old white girls in the same classroom, the twelve year old girls are well and truly into puberty, and the twelve year old boys are not, creating a profoundly disruptive environment, though not as severe as that caused by twelve year old white boys, and twelve year old black adult men in the same classroom.
But the biggest failure of libertarianism, the biggest failure by far, is marriage and the family. Libertarianism is basically incompatible with family formation, children, and grandchildren, with the continued existence of whites and east Asians, for white and east Asian women are psychologically incapable of breeding near replacement in a libertarian environment.
The problem is that for a man and a woman to raise their children together, to provide their children with a mother and a father, they have to form one household, no fences. But if one household, then one captain. The man has to be boss. Further, they have to be stuck with each other for incentive compatibility. Consent to sex has to be once and forever. If consent to sex is moment to moment, then marriage is moment to moment, and you get serial monogamy, which means that husbands have no incentive to care for and nurture their wives, and wives no incentive to please and obey their husbands. Which means that women get their way sexually until they hit a certain age and become cat ladies, and men do not get their way sexually, and means that children have only one parent, and a lengthy succession of violent and abusive step parents.
A libertarian solution to marriage and the family would mean two separate households with visitation rights. A lot of people are trying that today, and it is not working. This stuff just fails. Broken families, empty buses, hellish schools.
If you cannot solve a problem with fences, guards, and guard dogs, the solution is unlikely to be libertarian.
