Banning guns is the 'easy' part - enforcement and removal is the hard part

2. You are correct

And it is why I think the idea of a new and retroactive ban won't happen.

Even your idea of overpaying for them is problematic because in a ban, the black market value of them will skyrocket.

I think the more reasonable way is to just shift AR ownership into the same category as fully automatic machine guns. Still possible to own but with strict licensing requirements. Then give them a 5 year window to certify or surrender them.

It will still be a mess but has the benefit of actually giving people an option.

Unfortunately this is a pandora situation and I don't see the guns ever actually going back in the box.
