It kinda is. Paying something $10,000 cash strongly suggests you’re buying something illegal, or you got this money illegally (not necessarily unethically, but still illegally).
That the only argument you can find is « it’s none of your business » doesn’t exactly play against this ruling.
Since when?
Maybe I just want to buy a handsome dog that won a show?
> Since when?
Drug deals, money laundering schemes, theft, ransoms, etc. I fail to see non illegal way to obtain $10,000 cash. And if you can get it legally, just do bank transfers instead
The argument for reporting is equivalent to "you have nothing to hide" and privacy. This is another aspect of privacy.
Furthermore, they don’t need the details. What if I just don’t want the government or bank to even know that I spent $10K at “Smucks Sex Store Co.”?
Anyway, I hope you’re starting to see the importance of privacy and cash. Even if they’re ridiculous and silly to someone else.
