I agree that the law against "structuring" is a terrible law.
A pretty basic principle of a free society should be that you can be prosecuted for disobeying the letter of the law, but you can't be prosecuted for disagreeing with the laws you obey. So it had better be that obeying the letter of the law is enough to be free from persecution, even when your sole motivation is to avoid prosecution. The idea that you can have one law and then another law that makes it illegal to obey the first law when your psychological motivation is only to avoid criminal investigation and penalty, rather than to further the broad, vague purposes of the law, has pretty authoritarian implications.
This. If the government feel that the law as it is makes it easy for people to get around it by using cash withdraws at $9K a day over and over again, then come up with a new law. Something like $10K a day or $100K over a 30 day period has to be reported to IRS.
