It doesn't really go without saying. Otherwise pharmaceutical advertising wouldn't need copious safety warnings in every single commercial.

I don't think it's a good idea to take the President's happy talk at face value, but then I also didn't think it was ever a good idea to spend money on Trump University, or donating to Trump charities; on the other hand, enough people did that the matters ended up in court and the two branded entities mentioned above were both found to be liable for misinforming their customers/donors.

There are a lot of stupid folk among the public, and it is to them that scam artists like Jim Bakker or Alex Jones market quack cures. There's an appetite for quack cures because they seem affordable relative to the often-inaccessible costs of basic medical treatment, because we don't have a universal public health system in the USA. The sad fact is that people sell snake oil because there are fat profits to be made by doing so, even though most of us recognize such products as little better than placebos at best or dangerous at worst.

This is why we have product regulation, credentialing and so on; it's hard for people to personally assess the quality of every product or service and there are unscrupulous people who are willing to exploit that difficulty.
