In the NL we have an Anti-Quackery league
https://nl.wikipedia.org/wiki/Vereniging_tegen_de_Kwakzalverij (internationally you have the Quackwatch
https://www.quackwatch.org or Skeptic
https://www.skeptic.com).
Those organizations seek to eradicate superstitious behavior and profiteering from the medical world where selling anything that hasn't a proven effect is illegal in most countries in the world.
Any product making any seemigly " scientific" claim should be compelled anywhere to provide evidence.
The reality is that this is only true of the medical science (and even there companies are fined every year to have made such claims improperly).

If companies are held accountable for these claims (read the links please) why can't we require any company selling a piece of metal for this much money to provide the evidence that they are NOT providing?

When consumers see or hear an advertisement, whether it's on the Internet, radio or television, or anywhere else, federal law says that ad must be truthful, not misleading, and,
when appropriate, backed by scientific evidence. The Federal Trade Commission enforces these truth-in-advertising laws, and it applies the same standards no matter where an ad appears - in newspapers and magazines, online, in the mail, or on billboards or buses. T
he FTC looks especially closely at advertising claims that can affect consumers' health or their pocketbooks - claims about food, over-the-counter drugs, dietary supplements, alcohol, and tobacco and on conduct related to high-tech products and the Internet. The FTC also monitors and writes reports about ad industry practices regarding the marketing of alcohol and tobacco.
When the FTC finds a case of fraud perpetrated on consumers, the agency files actions in federal district court for immediate and permanent orders to stop scams; prevent fraudsters from perpetrating scams in the future; freeze their assets; and get compensation for victims.
IF there is any beef show it and show it well with the appropriate science to back it up, or otherwise just say " LeFreque looks nice on your flute for the man and woman of distinction" and nobody would bat an eyelid
