If you contend that you were not properly informed, prior to accepting the assignment of the SSN, that having one is voluntary for those who live and work in any one of the fifty Union states, and that by accepting a SSN you were waiving your unalienable, Creator-endowed rights, then you can declare the assignment to be unconscionable, fraud, and void on its face.

Revocation of an unconscionable contract is retroactive; anything predicated on an unconscionable contract is null and void, as if it never happened in the first place!
