True. Average people are sophisticated enough to understand complex financial instruments designed to scam them by an army of lawyers and MBAs trained at the finest financial institutions and law schools.
Also, we already let people engage in sports gambling (which is guaranteed to result in a net loss) and cryptocurrency speculation, (which is a zero sum game). I'd rather give people more options to invest in financial instruments that at least in theory have the potential to be positive sum, since we're not going to ban either of the other two any time soon.
