Probably not.
The reason is banal - any anonymity, or rather non-transparency of money flows, is a "violation" for the state. The banking system strictly complies with the regulatory norms of central banks, and cannot afford such violations, as it is essentially tantamount to revocation of the banking license. In today's world, even the "last aplot of anonymity of money" - Swiss Banks, actually canceled this "feature". And the culprits of all this are ... the people themselves! Because we tend to use GOOD solutions for bad things. I think in the modern world this trend (deanonymization) will gain strength
If we look back at recent history, we can see many examples where banks have done (and continue to do) what they want, because they know it will not have major consequences or problems with states or governments. How many banks have protected money from traffickers (of all kinds) or laundered those fortunes?. There are many examples, and this has not only happened in Swiss or European banks, it has happened anywhere in the world. And what have been the consequences? At most, the resignation of some intermediate position, they have never wanted to reach the top.
Banks and governments have always done what they wanted, it would not seem strange to me if they used privacy coins. Transparency laws are for others, the people.
It's silly to deny that banks, not infrequently, do very bad things.
I can't speak for all banks in the world, but two examples are enough for me:
- In my country, Ukraine, the banking sector was restructured in 2014 -2018. The reason is banal - high corruption, illegal schemes, and other things that the corrupt government has created. At first, the banks and their "patrons" tried to "solve the issue" at the highest level, but were rejected. It came to sabotage of the banking sector, which could have a very negative impact on the whole country. An example is the forced nationalization of the major bank PrivatBank. Its owner, after the schemes of embezzlement of millions of dollars from the state were revealed, began to threaten that "tomorrow he would stop the work of the bank", which meant millions of pension accounts and tens of millions of accounts of citizens. In the morning, the bank was handed over to the state, and the owner was put on trial.
- Switzerland, after dialogs with FinCEN (Financial Crimes Enforcement Network), decided not to bring the situation to a conflict and started to fulfill their demands. This was a smart move, otherwise we would have heard about the closure of many Swiss banks.
