That's quite wrong. And the reason is that you are assuming that superstition is all religious faith is about. And it's not about that by a long shot. What it's about is how it makes people feel about themselves in relation to their experience of existing. And that's as real as anything real you can name. Especially when you realize that "objectivity" in human terms, isn't objective.
You are raising a moderate level if insight into the physicality of existence way above it's actual importance. Because ultimately, what matters, is not our physical existence, or circumstances. It's our experience of it. Life for we humans is not primarily physical, it's experiential. Reasoned inquiry is a useful tool. But that's all it is. A useful tool.
You've done no such thing. There is no "objective reality" from the human perspective. It's an ideological fiction, like infinity, perfection, and justice. There is also no such state as the "purely conceptual", or "purely imaginary". These, too, are ideological fictions that you've invented to maintain the fiction of an "objective reality". All reality is experiential: physically, conceptually, and imaginatively.
