I do think what you're saying can be framed another way. What if we focus on the world instead of the individual? What would we see? The dilemma is over whether or not the world is capricious or coherent. A coherent world is predictable with rules. In a coherent world we believe that if we work hard, we will do well in life. We'll get good grades in school, find a good job, and so on. But what if none of that happens despite our hard work? Our belief would then be limiting us in some way. Better to be flexible (or have "no belief") in a capricious world, in a land ruled by unpredictability. Practically this is what I think you're talking about (when "asking about the possibility of living with no beliefs"). Correct me if I'm wrong. Maybe I'm way off target. What is it for Buddhists then?
