Let us not forget, though, that homeopaths could easily be so utterly incompetent that their dilutions fail to eradicate the original substance. As such, I'd be very cautious about making an argument against homeopathy based purely on the supposed physical mechanism :-)

But thanks, I didn't mean to imply you were agreeing with the nonsense, I just didn't (until your second comment) understand why it was muddying the issue.
