I agree that removing guns from the equation isn't going to fix any of the core, underlying, societal, problems, nor will it ever make violence magically vanish from society.

It will, however, significantly reduce the ability of individuals to murder, threaten, wound and intimidate each other, as well as significantly reducing the suicide rate. people are still going to be able to attack others with fists, with a baseball bat, with knives. But the number of people ending up dead or maimed from those attacks will be significantly lower, and the number of mass shootings carried out in schools etc would drop like a rock.

Some of the volume of gun violence will merely shift to other forms of violence, but far less of that will be fatal, and the overall level of violence in society will almost certainly drop significantly as well.
