Even if you claim that the outcomes are the same, you cannot claim that the paths are identical, that's just lazy argumentation that ignores the history of philosophy.
I didn't claim the paths are identical, and don't believe they are. I said the reasons are much the same. They both deny human nature. One relies on a level of altruism that doesn't exist. The other relies on a level of "rational self interest" that doesn't exist. Both rely on a level of honesty that doesn't exist. Similar reasons, less similar paths, almost identical outcomes.
> that's just lazy argumentation
No, lazy argumentation is presenting no argument but a link to someone else who says "Time forbids the treatment of that phase of the subject here" when addressing the matter at hand. There is no way to that anarchist (what we would now call libertarian) utopia but the same kind of revolution that led to communism's notable real-world failures. Furthermore, there is no way to maintain such a system and keep it from devolving into oligarchy other than to have a robust government to keep the four monopolies from re-forming. This "anarchy" in practice ends up looking a lot like modern socialism.
