In conversations like this, it seems like people fail to take into account the fact that the population does not include just able-bodied men.

If you go down the road of taking away all weapons, how is an injured person in bed supposed to defend against a robber who strolls into his house and wants stuff? Is the injured person just screwed, and oh well? What about handicapped people? What about elderly people? What about women who weigh 95 pounds? Are they just screwed too?

People who can fight well with their hands (mostly men) will be the only people who can defend themselves.
