Registration is the penultimate goal of the gun grabbers. It is a Necessary step in order to be able to confiscate firearms which is the socialist's true ultimate goal.
Firearms registration must be fought at all costs because not only is it worthless (Think Canada here) but it's expensive with a cost in the billions. However if all firearms were registered confiscation would be relatively easy as was done with "assault weapons" in california.
I personally think less Americans would comply than the Canadians did before they scrapped their system.
