If the Peoples' elected representatives decide to require Constitutionally-permissible firearms registration, then respect for the nation, IMO, morally obligates you and me to comply.
Wrong.
At that point your government will have totally nullified what little moral authority it has left, having made itself a despotic tyranny attempting to impose itself upon what remains of a free people. We don't care if your elected reps decide to do what they did to shove ObamaCare on the country and declare it 'legal'. In fact, we don't care if 90% of the country votes to become Communist and demands we abolish speech, religion, press and arms. At the point any of that happens, we no longer consent to be governed by such a system.
It will at that time, become our sole duty to refuse and resist compliance by every and all means at our disposal.
The radical Leftists that put Obama into power estimated back in 1980 that 30 million Americans would refuse to go along with their plans and would have to be exterminated - as in killed and dumped in mass graves.
How many of us are you willing to kill to see your utopian vision of gun registration and confiscation realized?
You better count the cost - because when you get your wish - we got nothing left to lose and you will have rued the day you ever put this stupid notion of yours into the public eye.
