their beliefs, whether rational or not, do inform their actions. And if we accept that the Federal Reserve's actions affect us (which, regrettably, they do)

Ok, I give you that. I just watched one of TDV previous videos where he explains the rationale behind his concept of Shemitah and Jubilee year. Interesting, but unfortunately almost essentially based on interpretation of symbols, coincidences, numerology, and market moves which can usually be made to "prove" anything and its contrary. Now I have to admit that there are some compelling elements, and the sheer number of coincidences is surprising which would make it difficult to bruteforce entirely out of thin air. I haven't checked all the facts and quotations, but if it appears to be timely and accurate, I might have to give that some more attention in spite of the fact that indeed really sounds like hocus pocus.

we know that the Rothschilds created and benefit from the Federal Reserve (ref, The Creature from Jekyll Island)

I'm not aware of the Rothschilds being present in person at the Jekyll Island Conference or directly involved at the Fed but I imagine that through investment in American investment banks like JP Morgan & co it's imaginable that the Rothschilds may have had a voice at the conference. Are there some serious research published on the subject that shows just how much control the Rothschilds had on the creation of the Fed?

Even if we dismiss the esoteric sciences as irrational, it must be acknowledged that cloaking one's plans in the language of those sciences to manipulate others into staying out of the way is coldly rational.

Actually, thinking about it, even Cicada 3301 uses symbols and occult phraseology as code in spite of the fact they are arguably a community of cryptographers, and there is nothing more rational than a cryptographer. One could easily dismiss what they do as hocus pocus on first shallow evaluation. So you have a point.

To be fair, I'm realizing with more research that TDV has been in the business of analyzing things from an occult perspective since a few years already. I wasn't a follower of TDV until he started posting on Steem, so the transition from level headed no-nonsense anarchism (which I am entirely supportive of) to a sudden unexpected delving into occult conspiracy theory threw me off considerably. Now given that he has been at that for years, and it seems to be strongly associated with TDV brand, I'm not quite as critical anymore.

However I think that TDV shouldn't mix discussions about anarchy and this highly speculative symbolism based financial analysis that bears in fact very little relation with anarchism: government is crap regardless of the reason it is in place and regardless of whom it actually benefits to. It's even more problematic that Jeff seems to be rather influential in the ancap scene, so without proper separation of concerns like publishing anarchy related content and Shemitah/Jubiliee theory under different brands, the risk of turning off would-be-anarchist prospects is high. Anarchism is its own quantity. It's a clean, lean, rational approach to governance and economy. Associating it artificially with the kind of thematic which, in your own words, "the average person will dismiss it as a bunch of hocus pocus" doesn't sound like a great promotion strategy.
