REAL ID Act starting to unravel

According to this post at Malkin's blog:

• The Real ID Act allows states to give temporary drivers' licenses to:

  -illegal aliens who have been granted a hearing for asylum,
  -illegal aliens who have applications pending for temporary protected status, and
  -illegal aliens who have applied for amnesty under the 245(i) program.

Yet, MM still "strongly supports" the bill, though she admits it would be better without loopholes.

I don't get what the bill accomplishes with the aforementioned loopholes included other than to force American Citizens and legal residents to conform with the precursors of the inevitable National ID card.

What is so difficult about stipulating that only people known to be here legally may acquire driver's licenses? Not people who want to be here legally, not those who apply to be legal, not those whose status is not known, but only those people who were born here or those who have gone through the processes to gain official legal residence status.
