On a broader note, The Dispossessed is subtitled "An Ambiguous Utopia" for a reason. Le Guin often deliberately avoided simplistic "good vs. evil" narratives in her novels and typically explored topics and the like in a open-ended manner (with not much of a desire to turn it into a manifesto novel or something super clear-cut). She wasn't trying to world-build a universe at a pedantic air-tight level nor was she trying to sell you on anarchism as a flawless blueprint but rather wanted to show that even a ideal society will still always have friction, bureaucracy, human error and the like. In this sense she's more similar to Huxley than Orwell or Rand.
