“It would break the covenant of “governing by the consent of the governed”. At that point, all bets are off.”
That has happened many times over the years. It happened the very first time that the government made laws about the restriction of ownership, background checks and registration of weapons. There has been no uprising. Why would there be an uprising if the government enacts more gun legislation?
There won't be an uprising.
Back when there was an uprising, the citizens didn't wait for the govt agents to come to individual doorsteps. The mere presence of the forces of the king on American soil, was enough.
Paul Revere didn't say "molon labe, come to my house and I'll put up one hell of a fight."
The enemy is on American soil. What do we do? Pay whatever is demanded. Pay their salaries. Pay for their vacations. Pay your licenses and registrations and health insurance and whatever else they tell you to pay for.
Confiscation would be many orders of magnitude above all other gun laws. It would be a violation of the 2nd, 4th, 5th, and 14th amendments.
