Lol, so your essentially saying society needs forced education to enforce libertarian ideals, and then you go on to say that compulsory education is slavery? Make a choice man.
No, ! Without some kind of mechanism any population will eventually abandon whatever current ideals. Governments use forced education. Libertarians have this problem they ignore.
Coerced education is Harm - this is unacceptable. Ideals will always change - that is inevitable evolution. What is not acceptable is people evolving to Harm each other.
Certainty is a very tough target. Persuading people to quit wasting life+resources Harming others and begin using those resources for Learning may be good enough for evolution now.
