The reason to remove such products is because they contain dangerous agents that aren't being disclosed. The same would be said of any scientifically well-validated product that was tainted. If bottles of paracetamol/acetaminophen were contaminated with toxic mold, those should be removed too I think.

I personally think the FDA should be more focused on these kinds of things — contamination and labeling fraud — and less on regulation of efficacy or access. We need more access and competition in the US, not less.

I'm definitely not assuming that homeopathic medicine is incapable of harming people, but for the sake of this specific argument I think it's reasonable to assume that we could find something that isn't especially harmful to fill the role of giving people who don't read the labels something to take.
