This depends on your social philosophy. Do you believe consenting adults should be free to engage in whatever victimless acts they choose
Your activities are not victimless. Fraud is not a victimless crime. And ethically, even if you have a little "for entertainment purposes only" sign in the corner, you're still being unethical if you know 99% of your customers come in believing it's true.
or do you believe the government should babysit and decide what's best for people?
I support freedom to do whatever stupid things you like. But not to harm others by fraudulently gaining other people's money based on lies. Not accidents, or misunderstandings, or foolishness believed in wrongly, but active likes the perptrator knows are false and knows the "mark" believes are true.
I say yes, the drug dealer should accept payment
Assuming he is selling a drug of fairly well-known and well-defined quality. That some people have called themselves a string of letters called "government", picked up weaponry, and threatened him with violence if he does this does not make it unethical.
What makes it unethical is if it's unpure, or of a non-standard strength, to what would be commonly expected by the buyer.
Personally I'd find it unethical to sell drugs to an addict, harming them, but I'd rather it not be illegal than to grant the government the power to make it illegal.
I'd rather this be legal and regulated so people aren't getting shot in alleys, but I believe that people should be free to engage in whatever victimless activities they want, be it sex, drugs, or psychic services.
No I don't do any drugs except alcohol.
Sex and drugs are consenting activities. Psychic services (portrayed as real rather than entertainment) are not, because they are fraud.
Should Sylvia Browne be able to tell a customer she has a secret financial investment, only $1000 to buy in, when in fact she just plans to pocket it and spend it on Hardees Thickburgers and Burger King Triple Whoppers with Cheese? If not,
why not? How does it differ from telling someone you're giving them a psychic reading, with the apparently legitimate expectation they'd have that it's real and reliable?
