Whether any US water district is really doing this seems debatable anyway. Maybe this is just a consequence of the poor state of search engines, but every source I can find claiming specific US water supplies contain unsafe levels of chlorine seem to be exclusively limited to companies trying to sell you expensive filtration systems you almost certainly do not need.
That's a strawman, for sure.
Doctors have a lot of education, and gain a lot of experience over time.
What I pointed out is that the studies are not enough. Where they leave off is where a doctor needs to be able to apply their education, experience, and knowledge of the case to make progress. Doctors are trained to apply scientific approaches to bridge the gap between the broad science and the individual patient. The big health co's do not like doctors doing this because it takes time and is expensive. So, they tie their hands because they only want the doctors to focus on the easiest fixes that solve the most problems.

No. Really, I mean it. Doctors are trained in textbook approaches, not in the scientific method. The less creative, the better the doctor. That's precisely what evidence-based medicine is, and it's what allowed us to leave the Dark Ages of paternalistic medicine.

We tie our own hands. With guidelines. Yes, the system is tuned to a limited investment of time and money in each patient for distributive justice reasons, but guidelines are (mostly) there to discourage crackpot medicine.
But hyphoteticaly...
if I'm an outlier, and blind test is made on only me, and reveals that I am sensitive to chlorated water.
...I would count that as evidence based.
> It has been shown to be safe and effective for most people.
And yet it wasn't until I was well into my 30s that I learned that not cleaning your shower head often enough or thorough enough can block the effects of the chlorine and spray aerosolized bacteria everywhere.
It doesn't matter what kind of medicine you have when there are plenty of problems that would be prevented if not for the obscene asymmetry of information and poor cultural health habits. But as long as big tech continues to believe that steering people toward political propaganda is what's best for society, that will be the narrative of the day rather than real progress.
A key concept and solution here is 'precision medicine', tailoring medicine based on more precise information about the individual.
I'd be amazed if somebody was really sensitive to chlorine, to the point where typical municipal water caused rashes. After all, all of us contain 80grams of it and consume 500mg/day.
Take a substance like chlorine. It is put into municipal drinking water because it kills things - things that can kill us or harm us. It is credited with making municipal water a lot safer.
It has been shown to be safe and effective for most people.
The key is most people. Some people, at the edges of the bell curve, cannot tolerate chlorine. If they drink water with it, or bathe in water with it, it harms them. I have family members who have this sensitivity. Since moving to a place with well water, their health has improved immensely.
If you were to be guided only by studies that show the safety and effectiveness of the chlorine treatment, then you could overlook the fact that some people are outliers.
Evidence based medicine will guide you to things that will work for most people in a given situation. However, for a specific patient, you may need to depart from that evidence.
Limiting doctors to only evidence based approaches prevents them from treating specific patients.
