- US haven status undermines despotic regimes by denying them data on citizens hedging their bets with offshore accounts. This provides the US leverage, intelligence, foreign direct investment & tax revenue.
- Offshore dollar pools (eg. Eurodollars) are problem enough for the US Treasury & FED's monetary policy. Absent US haven status this problem would be far worse.
- The secrecy doesn't much apply to US citizen and less so once the Democrat's $600 bank account reporting requirement is passed into law.
