> There's no room for violence in the future

I'm sure humanity will find some

Since forcibly disarming someone is application of violence, I fail to see your end-game.

Even Star Trek had phasers. Weapons will exist as long as there is a need for a person to defend themselves against a foe.

How do you plan to arrange that?

Be specific.

Is a hammer a weapon or a tool?

Is a military mortar a tool when ski patrols use it to save lives by safely triggering avalanches?
