Money laundering is the conversion of ill gotten gains into something which looks like legitimate income.

For example, if you have a bunch of cash, you can't buy a house with it because you're going to have to explain your source of funds.

So running a cash-only business with a lot of "customers" is a way you can turn cash into justified business income. That is money laundering.

HOWEVER, if you have a bunch of cash, and I have a bunch of cash, and we decide to exchange notes because don't like the government tracking us by scanning the serial numbers on them, that is NOT money laundering. If your cash was unexplained before, it's still unexplained after.
