I tend to agree with you.

I have a bank account with about 5K euros on it. I have not touched it in 20 years (no deposits, no withdrawals). I earn tiny dividends on it each year.

I got a request from the bank 18 months ago to provide my tax return to them. I said no, why? They threatened me to confiscate my account (orally, on the phone). I replied I understand you need to ask info from me, by law. But if you don't get the information it's ok too, afaik. And there is no possible way that I can launder anything if the money is just sitting there.

I will see what happens...
