There isn’t really. Most people are unaware that most crash transactions and withdrawals anywhere close to those amounts will almost always have to be reported to the government of whatever country you’re in. But, you know, EU bad…

There’s no wholesome reason to need 10k in cash. Even the examples here of paying for an abortion is a problem with reproductive freedom and not cash. You’re not suddenly going to get away with it because you “sneakily” withdrew 10s of 000s in cash, right before you travelled to a state where abortion was legal. Political donations can be made in small, repeated sums. Specifically, as they dont sell large value items.

Unless you’re a hired assassin, a paedophile network, a corrupt politican or a drug cartel it’s not going to effect your business.

In reality, most of the nay sayers are people who take cash payments for the work they do to avoid paying the taxes the rest of us have to pay, for the things we all use.
