Ask HN: Why stop at banning Nuclear Weapons?

Just watching Canadian Bacon right now and it got me thinking... Excluding hunting being a human right and a piece of our history... Why do we as a human race allow for the production of any weapons whatsoever? What benefit is there to owning or using a weapon? We are talking about banning automatic weapons in America recently which is a step in the right direction imho. But why stop there? If we collectively prohibited all countries worldwide from producing weapons like tanks, rocket launchers, etc... There would be no need for any country to own or acquire similar defences.
