There isn't a bank in the World that will not comply with local laws.
The AMLD is not secret. You can read it here: https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=celex%3A...
The AMLD is not dissimilar to any other anti-money laundering regulation in the World, including the USA, Switzerland and others.
If you have large cash flows, you will be asked by banks to explain the nature of them to ensure they are not illicit. If you are not prepared to explain that, the bank is not under any duty to do business with you, and depending on the nature of your transactions may be required to report them to law enforcement. If you do not answer to law enforcement, they will likely start an investigation to ensure you're not involved in organised crime.
Once your bank or law enforcement are happy you're not involved in organised crime, they'll leave you alone.
That's it.
If you are not involved in organised crime, but not prepared to explain that, yes, law enforcement are going to be interested and banks may not be prepared to do business with you. This has been the case for hundreds of years, it's only now there are more strict guidelines and rules around when suspicions should be raised and reported, and how they should be investigated.
I really don't see what the paranoia here is actually about.
