I would reckon your resistance would last until a Hellfire turned your home, pickup and guns into a flaming pool of spilt diesel, charred meat and plastic slag.
What?
If the Government starts using Hellfires fired from drones or otherwise, on citizens, don't you think we're long overdue for hitting the reset button?
I don't care who you are, if you think you can justify dropping bombs on Americans to force a gun confiscation agenda, you are sorely mistaken. And, yes, that is *precisely* what you just said.
1. Forced confiscation enacted (even if remunerated, it's still forced, by threat of prison if you don't comply - armed men come to take your belongings)
2. Gun owners resist giving up their property and means of self-defense
3. Government starts launching missiles at gun owners homes who resist.
I'm really shocked at your train of thought, there. If the government started drone or assault helicopter strikes against people's homes in the US we're WAY over the threshold of what defines a tyranny. At that point it's time for @100 million gun owners to hit the reset button, so our people aren't being subjected to modern military assaults for offenses.
And yes, if it came down to it, we have WAY more gun owners than the government has hellfires. (Also, off-topic, but I have a suspicion that some of those missiles would be turned back at the people giving the orders, if that order came down.)
Recently we've seen armed groups of civilians stand up to the Federal government and the Federal government has stood down, to avoid bloodshed (BLM standoff, etc).
Don't overlook the power of the 2nd amendment... what the original purpose is for, and how important it is that we retain it intact for future generations.
You can't *always* count on this country being a shiny, happy place to live. 50 or 100 years from now our descendants may very well have a use for great-grand-dad's belt fed 50 cal or stack of AR-15's.
