National ID is more than a mere considered possibility.
Federally required REAL ID is just National ID by another name. The compliance deadline for REAL ID has merely been pushed back slightly.
It is still the law.
"Because states may have difficulty complying before the May 11, 2008, deadline,
DHS will grant an extension of the compliance deadline until December 31, 2009. States that have received extensions will, over the course of the waiver period, submit proposed timetables for compliance.

I believe it wont be long, before cash is no longer an option, and in fact the Fed has also said the same.
Your sex/gender listed in the National Database, is already linked to your Social Security record, which has long contained your name and sex at birth in addition to your current name and sex.
All names you have ever used, your name and sex at birth and your current name and sex, remain forever in your Social Security record and cannot be expunged, and getting a new SSA record is nearly impossible, being both costly and time consuming, even when you can meet the extremely stringent requirements for doing so.
