Okay – let’s say we have a magic wand and can magically make ALL guns just disappear – cease to exist. Gunpowder technology no longer exists and we cannot easily recreate it. So – now there’s no guns at all. What happens? As you mention – the criminal element (typically composed of young, strong, hardened and violent men) have a monopoly on force. They can use their greater physical stature to beat up and rob anyone they please. They will invent or acquire melee weapons to further their criminal aims. Even if law-abiding people are allowed to keep melee weapons for defense (don’t laugh at the idea of a “sword ban” – many countries have done exactly that in the past, and the UK currently bans so many things that could be used as a weapon its frankly amazing to me that there’s ANY crime at all there! ) – swords and other melee weapons take a great deal of skill, strength and practice to use effectively against a similarly-armed attacker.

The gun-grabber’s failure to acknowledge human nature just shows me that their collective heads are in the sand. (Or perhaps somewhere just as dark but a little more pungent)
