I absolutely take advantage of the placebo effect. But that is for myself, not as a healthcare provider giving it to anyone else, and it would be unethical of me to sell placebos to anyone else as anything other than a placebo.
And even if it doesn't involve profit, there's a difference between being okay with knowingly using the placebo effect and actually thinking that "like cures like" and a million fold dilution is super duper strong. There's just a refusal to accept basic logic there when not even acknowledging that there's unlikely to even be one molecule of the compound left in the super diluted stuff.
