> They're only targeting cash transactions so unusually large that it's hard to imagine a legitimate purpose for them.
I am saying that millions of cash transactions of this size take place every year and that the majority of them are legitimate. Whether or not you can think of reasons why people would use cash in that amount is sort of irrelevant.
Can you give me an example of a common, legitimate $10,000+ cash transaction? Elsewhere I gave the example of my mom transporting transporting a ton of money in cash for the initial down payment of a house, but that was 40 years ago. Nobody does that anymore for good reason; there are far easier, safer and more practical ways to handle that kind of transaction.
