Very nice. "I decided to revoke my Social Security number"
There is no procedure for doing that...

The Notice of Mandatory Exertion of All Unalienable Rights is an attempt by the individual to declare himself as a sovereign citizen of Michigan, but not of the Unites States. As stated previously, however, the forms have no legal effect and the individual cannot withdraw from the Social Security program
