Are you arguing laws against money laundering are immoral? Because they are a practical requirement in order to levy any type of income tax. Or are you claiming that Silk Road style sites are only illegal because of immoral laws? I get that the HN crowd generally has a libertarian and anti-prohibition bent, but outside of illicit drugs there are some inarguably horrible things being sold on those sites like child porn and murders for hire. Doesn't the government and law enforcement have a moral requirement to combat that?
