“I wonder just exactly how a law against using cash over a certain amount would affect a terrorist operation.”
It doesn’t.
Ebay and Amazon are both being used to launder and transfer money to criminals and terrorists worldwide. Look for yourself, it is very easy to spot.
Of course they won’t use this as a tool to eliminate the employment of illegals. They will be allowed to bypass the rules.
Like when someone is selling a T-Shirt or toy for $900?
I see that on Amazon many times.
