What lie is required? You buy 1000 pizzas a day from your pizza store, with cash you already have. You report all that income to the IRS. Where's the lie?
Edit: Keep in mind if your original money you evaded taxes on, that's already a crime. As is committing crimes, if that's how you got the money. "Laundering" is just a non-crime used to make LE's job easy, expanding power and reducing privacy. AML and KYC laws are an affront to liberty.
