Not entirely wrong. I think it's entirely possible for "free will" in the sense that it's normally talked about to not really be a thing. After all, we're taught about "nature vs nurture" in psychology, that is, learned vs inherent behaviors passed through genetics. I think what we call "free will" is itself curiosity manifest from random decision making. The overwhelming vast majority of our decisions are based on learned behaviors though, and decision making itself is known to be a cognitively taxing process; so we're predisposed to routine, simplification, and working with proxies.
Edit: to your point about needing validation: the desire for acceptance is simply put, the desire for a positive feedback response on a personal or societal level. Remember, our brains are big reinforced learning machines and crave feedback as quickly and unambiguously as possible. The desire for acceptance is both a thing that keeps behaviors "in-line" with societal expectations while allowing for changes in those behaviors to shape societal behaviors (and expectations) over generations (time), and therefor make progress, or at least change.
