As a fellow dirt eater, I agree, but lest we forget how we got to where we are today. Here is a brief history of drinking water (an easy read), and lest we forget the Broad Street incident? "There was a major epidemic of cholera in London in 1854; Dr John Snow demonstrated that many cases occurred among people who drank water from a pump in Broad Street; those who obtained water from other pumps did not contract the disease. The pump handle was removed and in that area there were no more cases of cholera. When adequate water supplies and sewage systems were installed and slums were cleared, the epidemics abated. " It's outlined in more detail here, and is also an interesting read.
"By the 1920s and 1930s, use of filtration and chlorination had virtually eliminated epidemics of major waterborne diseases such as typhoid and cholera from the American landscape. "
Here is another link to a good CDC article.
These items are relevant in that leaving the problems unchecked to simply rely on immune systems did nothing to alleviate them. Our immune systems have a life of their own, as do the infectious entities, whether they are virus, protozoa, or bacteria. Thus while we can make a conscious effort to not get sick, sometimes it is out of our hands to simply rely on our immune systems to be the firewall for the rest of our body.
This subject does not deal in absolutes though, each case is different, I'm just adding some food for thought.
