Without taking a position on whether I think <MCRed> is right as a policy matter, you're responding to a different point.
<MCRed> is arguing (admittedly in a rant-y kind of way) that the U.S. Constitution is a document that grants limited and specific powers to the federal government and reserves the rest for the states and the people. That argument says those powers do not include the ability to regulate money exchange. An implication of that argument is that nearly all law enforcement would be left to the states -- so your hypothetical sex slave ring would be prosecuted by the states, and in fact every state currently has a law on its books making such a conspiracy illegal. And in fact most criminal prosecutions are already done by state governments.
Again, I'm not saying what I would prefer as a normative matter, just that it looks like you're talking past each other to some extent.
You're right, I am responding to a completely different point because I didn't really want to argue about what kind of powers are and aren't granted to the federal government by the Constitution. etchalon did a great job at that: https://news.ycombinator.com/item?id=8277608
Ignoring the legal system and the Constitution entirely though (purely for the sake of argument), it makes practical sense that for offenses that constitute multistate or multinational money laundering, the federal government would be the most appropriate enforcer of the law.
It's sad that you don't care about the quality of arguments or what the truth is. You just seem to care about what fits your ideology, which I'm sorry to say is fascist. (I await the time that another term is coined for this ideology so that I can stop using that one which people presume is a cheap insult rather than a precise description of an ostensible capitals society where the government has unlimited regulatory power.)
I submit to you that the "crime" of money laundering is one you're guilty of. I know for a fact, under the law, the way it is written you are guilty of it.
Thus you are advocating for your own incarceration.
