I am also a long-time LW lurker, and this thread finally made me open an account. I’ve read most of the main Moldbug sequences (Cathedral/neocameralism/economics) over the past few months.
I was very pleased to find that this thread existed, particularly in the context of the phenomenon identified in that essay which coined the term ‘insight porn’. I had previously expended many brain-hours pondering the nature of this set of closely affiliated ideas, and I still don’t think I have entirely satisfactory answers.

I believe that this statement was not an endorsement of libertarianism, but rather a sop to libertarian readers, based on my knowledge of his style.
Moldbug draws a clear distinction between libertarian policies, which he believes meet straightforward criteria for effectiveness and sanity, and would (not ought to, but would) be implemented by a Responsible Government (see: neocameralism), and libertarianism as a political philosophy and movement.
He identifies the fundamentally Sisyphean nature of advocacy for libertarian politics within a democracy, and also the untenable assumptions of the Rothbardian non-aggression theory of natural rights, which, barring some bizarre change in the present technological-military détente, makes the absence of a geographically-based state with a monopoly on violence equivalent to ‘money on the table’.
