This could probably be explained by a sufficiently detailed computer simulation of human society.
Some people, those with the lowest amount of faith in unsubstantiated beliefs, debunked homeopathy according to their own standards. They proved that it did not work better than the placebo effect, one of their existing and well-substantiated beliefs, resulting from a through examination of the simple question: "What if the effects of this treatment are all attributable to the patient believing that it should work?"
A large fraction of humanity, probably an overwhelming majority, has not been trained to examine the world scientifically. Many have been indoctrinated into religions or nonscientific pedagogies from a very early age. For those people, it is not sufficient to prove that a treatment does not work better than placebo to stop using it. It must be proven to not work at all.
Clearly, homeopathy activates the placebo effect. Thus, scientifically minded people reject it as a treatment. For everyone else, they find that it either works for them, or they can move on to a different placebo that does work. They may be wondering why scientific people work so hard to debunk placebos, because they are really just limiting the number of placebos they could be using.
