@PATAX Well, they did it four years ago, as part of the National Defense Authorization Act, better late than never.  And FinCen dates back to 1990, 

"FinCEN was created in 1990 to support federal, state, local, and international law enforcement by analyzing the information required under the Bank Secrecy Act (BSA), one of the nation's most important tools in the fight against money laundering. The BSA's recordkeeping and reporting requirements establish a financial trail for investigators to follow as they track criminals, their activities, and their assets. Over the years, FinCEN staff has developed its expertise in adding value to the information collected under the BSA by uncovering leads and exposing unknown pieces of information contained in the complexities of money laundering schemes."

All of those things you claim "they" are doing, required a majority of elected representatives to approve. And they could always have repealed them if they saw a problem.  I'm sorry you have to live in a democracy.  The Constitution does protect some minority rights, but Dobbs took away your right to privacy.
