If you had a button you could press which would magically make all weapons on earth disappear, what will you have achieved? You would have just transformed the power structure and taken the might away from those with physical weapons, and delivered this might to those with big muscles and the ability to coordinate with others like them to give you a good beating.

But all that aside, I talk about magic buttons because such a law would be impossible to enforce, and certainly not globally.
