>Financial adviser charging substantially above-market fees to recent widows, who lack experience in finance
As long as the financial advisers statement is along the lines of "this is the service I provide, these are my rates", with no lies about saying how his rates are the best or lying about what he can actually do, absolutely no problem.
That doesn't mean that he is of a moral upstanding character, but he certainly shouldn't be banned from setting his own price.
>Selling heroin outside of a drug rehab clinic (All information available & understood, but under compromising circumstances)
This one is tricky, because unlike online sports gambling, this ties into other things.
My answer would still be yes with the following caveats
* The heroin seller is FDA certified and not making the drug at home where he can accidentally mess it up and kill someone that is not expecting to die.
* We have a system of dealing with people effectively who turn to drugs. Id be 100% for state/government funded drug camps where anyone can either voluntarily enter, or get put there if their drug use causes them to be a public nuisance. They can stay there, get shelter and food and basic first aid for free, and get all the drugs they want, with 2 caveats: no advanced medical care (if you OD, or have a heart attack, you die), and the only way to leave is to go through a trial reintegration program where you get support for getting off drugs, get put to work, and do this for a year before being let out.
