I don't want to argue that religion has no place. Not at all. But your description, though I understand your thinking it would be a great loss if we did not have it, does not cover all; and I would like to suggest that you consider that you in fact have it backwards in terms of what is most important:
Romans 1:20
"
For since the creation of the world His invisible attributes are clearly seen, being understood by the things that are made, even His eternal power and Godhead,"
In this way God is perfect in guiding even the unchurched. But men by religious means, though they may have carried a significant amount of water, have done so in a manner far from perfect, even hindering some and leading many astray.
As an example of proper order and perspective: We could revere Moses for bringing forth the Commandments, or we could revere God who wrote them with His own finger. True and pure religion revers God without any reverence to itself.
