It's physically impossible. There are more guns than people. What are they going to do? Double the size of the military and go house to house, shooting Americans who put up a fight?

It's not even a remote possibility but the NRA would like to keep gun owners afraid forever. Keeps them in cash.

You seem to be focused on the title of the meme. It's just a hypothetical. Also, It's not just about the money. The NRA's opposition are quite formidable. However, this goes beyond the scope of the meme itself. Guns are highly regulated and controversial. The argument is that personal digital storage devices will follow suit.
