It is not "just" as effective. It is merely effective enough that a killer can put it to good use if they don't have a gun.
Killing people is something that is easily managed without a gun, as thousands of years of human history has shown.
Guns are more effective, but all the extra effectiveness is just overkill when the bar is so low to begin with.

Because any limit on self defense runs headlong into
Strict Scrutiny, and there is no valid reason to prevent people from having guns.

Need doesn't apply to me. I'm an American. If I choose to have a gun, I have the right to have one.
