There is harm with alternative medicine. Just a few examples:
In addition there is financial harm. People waste money to substitute medicine with alternative treatments. Also in the UK for example tax payers’ money goes to crap like homeopathy.
There is also societal harm in that many alternative practitioners can be anti-anything-that-is-not-natural including vaccines. I used to go to a chiropractor who told me the body should be able to heal itself and that vaccines are not necessary.

The issue is that there are people that should not be giving medical advice, and sometimes they give bad and just outright wrong information to people. Bad information and deception is not without its consequences.
My post makes it clear that there is potential for harm, but he burden of proof is on those making the accusation in each case. I can just as easily point to people harmed in scientific medicine and these are dealt with in the same manner with the same burden of proof.
Your economic argument falls completely flat in my case because I am in a different country where the medical costs are so debilitating half the times I have turned to it has been a terrible mistake. So much so that, medical professional = economic vampire, is the unavoidable lesson of my experience.
Would I support the kind of socialized medicine you have in your country? Damn straight I would!
What country are you in?
