It's not the "financial system" that comes and hunts criminals with guns, but police, acting based on what laws they seen has been broken. And stealing $3 billion is as illegal if it was Bitcoins, as if it was Euro or USD.
So in your scenario: The 3 billion will reappear at some point and they will raise flags. And at that point there is a convenient rendezvous point between law enforcement and the perpetrators. And we can all quibble about whether the authorisation is appropriate or not (not all "requests" are requests and most won't even need anything close to a court order). But it's damn convenient to follow the money
The "financial system" is even more central a player when you consider the universe of potential crimes. Why don't drug dealers put their illegal and ill-begotten money in the bank? It's because the bank is obligated to ask a million questions, and occasionally, to freeze accounts. Why don't North Korean hackers request payment by bank transfer of USD? Because those payments can be put on hold or reversed by the financial system, which is a tool of the "police" in a way that Bitcoin never can be or will be.
The "financial system" is literally a technical system which has been effectively deputized by the "police", and as a matter of technical reality the "financial system" enforces the laws in ways that bitcoin (and exchanges, custodians, etc) are designed to prevent. Financial systems sometimes return stolen money and enforce laws with the involvement of literal police, but mostly not.
Some may not like the laws, and they can argue for why bitcoin is great. But if you like the laws, you should grapple with the fact that Bitcoin was designed to robustly foil the laws. On purpose! This property is called "permissionless" or "censorship-proof" by people that like it.
