Except in limited and well-justified cases (for instance, you are a Russian ultra-wealthy person who wants to have a Plan B if Putin doesn't like you anymore), these types of passports have historically been associated with war criminals, drug traffickers, and individuals seeking to evade taxes. Financial institutions and government authorities are well aware of this reputation. Acquiring one of these passports is often seen as a major red flag, casting suspicion not only on your businesses but also on you personally. In most cases, they simply aren't worth the risk or the money.
