Government doesn’t have the people or materials needed to totally control everybody in the US.
That’s a given.
Remember, if anything happens to disrupt our lives to that extreme, government is not immune. Nor is military.
They still worry about themselves, their family, their neighborhoods.
When you speak of “organized resistance”, it’s like you’re talking RED Dawn nd Wolverines!!! and that kind of think.
Which is noble but stupid. The only way to get through is to keep your mouth shut. Zip your lips, and stay low.
Don’t say anything and NEVER draw attention.
The biggest problem if you live in an out of the way place (or even if you live in the city) would go like this: you say something to a friend or neighbor.
He or his family is starving or needs medicine.
Next thing you know, you have your door kicked in and you are dead.
Meanwhile, your friend suddenly gets his food or medicine.
Even if you keep your mouth shut, anyone who asks you questions is probably coming for you and may need to be handled in advance.
