Agreed on all points (especially about chiropractors calling themselves doctors). One major driving force behind quackery seems to be the ability to assert that it's banned because it works so well it would put pharma out of business. But as we've seen from the dire warnings and non-banning of Ivermectin, these things can now burst into mass poisonings in a matter of days, much faster than any regulatory body let alone public messaging campaign can keep up.
