That's overstating my argument.

Let me boil it down further (at the risk of some nuance being lost): Firearms are useful, but not extremely useful.

1) Firearms are not a panacea, and there are plenty of other tools that are at least as important, and a few that are more important. Lack of clean water is a lot more likely to kill you than lack of a firearm.

2) Rather than focusing on personal defense where everyone needs one or more firearms, a better approach is community defense, which at the Dunbar Limit (~ a small village) scale requires at most 1/3 of the firearms, so the resources that the other 2/3 would represent can be spent on other things.
