The details matter. There are societies that have eliminated civilian ownership of firearms (nearly entirely) without becoming terrible places. There are no societies that have eliminated all restrictions on government searches and seizures of property without becoming terrible places (they're all either dictatorships or security states or both).

You're glossing over something. Well, two somethings.

First, you're confirming for me that the goal is to eliminate firearms from private hands. Thanks!

Second...you're assuming it can be done. What gun control advocates aren't getting is that regardless of how you feel about guns, the horse in terms of removing them from American society has left the barn. It's not practically possible to confiscate them all. Not. Going. To. Happen.

This is where details matter. Are you prepared to have a 100%, locked down border and MUCH tighter controls on our ports of entry? Because if you aren't, and you're not willing to go to the maximum to seal both, then you're going to continue to have weapons run into this country with near-impunity.

I'm also not going to grant your point about other countries "not becoming terrible places to live" because those comparisons do not apply at all to the United States. Neither in size nor in cultural makeup. It's just not valid to say, "Well, Japan is okay and they have very limited private gun ownership" because Japanese society is very different than American society. Ditto all the other places you mentioned.
