Airborne pollution can travel long distances, so the water from rainstorms over the open ocean isn't much better than that near coastal areas. Go ahead, get a bucket and catch some rainwater in, and cover it and leave it sitting in the sun for a week. It won't be the "clean" water you think it is after that time is my guess. Plenty of pollen, microbes, mold spores, etc in that rain water.
What you say about rainwater is true but how do you think it compares to water at many foreign and some domestic marinas?
