If our universe did not have the kind of structure that appears in a causal model, then our reasoning would not function properly. Induction would fall completely flat, and I don’t think our brains would work right. We probably wouldn’t exist in such a world, but if we’re taking into account anthropic effects… well, I’m not even sure a human could survive long enough for a single conscious thought, since their state at time t+1 wouldn’t follow from their state at time t.
After skimming others’ replies, I’ve realised that I’ve answered a different question. To answer this one: no, but we’ve got no way of reasoning about or utilising anything else, so it doesn’t matter. That there are no uncaused causes of real things (a weaker claim) does meaningfully constrain experience, though.
