Such mischaracterization is a giant red flag for knowing you're dealing with groupthink. Moldbug's points venture into forbidden thoughts and attack the national religion, so the knee jerk reaction is to regroup at ad-hominem by ascribing simplistic straw men.

FWIW, reading "A Gentle Introduction to Unqualified Reservations" made me identify as liberal. I wholeheartedly agree with Moldbug's analysis of the arrow of time and condemnation of the machine(s) of USG and the Cathedral. But I believe he unjustly discounts the idea of distributed force wherein aggression is unproductive, and IMHO making that work at lower levels is a better goal than the federated centralization of take-it-or-leave-it fiefdoms. (Then again, this growing feel-good "SJW" cancer has me rethinking how enlightened such a society could be, but I digress...). He also discounts how technology has made subjects ever-more transparent to their rulers, with a simple handwave that rulers wouldn't be interested in unnecessary policing. (If I am guilty of oversimplifying here I apologize - it's been a while since I read him and I'm recalling my main takeaways.)

I don't believe in Urbit for similar reasoning - it seems like its entities are opaque objects where the only primitive is composition, and punts to delegation for solving the hard problems. I'd previously gone down a similar "immutable universal code" fugue with r6rs as the basis and eventually considered it a dead end.
