I agree but the unanswered question still remains. Who is going to say goodbye to their family, job and the good life and go to prison, especially if not enough others will do the same.
We as a society are conditioned not to interfere, even if witnessing brutal muggings, assault and rape in plain view.
Not everybody has to be active combatants. That did not happen in the revolution nor the first civil war - think it was like 10% involved actively in CW1. In the revolution it was less like I think 3% - hence the 3% talk.
Plus, its an increasing number as it progresses, every tyrannical act of the oppressors will create more opposition. The more brutal it get the more will go active.
As to your first question, if they are coming for your guns all you listed are going away regardless.
