> Carrying firearms around is already a non-issue in most of the world, so it's pretty weird to focus so much on it.

Not sure which places in the world you are referring to, but it's illegal in most places, and where it's not illegal, it's generally frowned upon to be carrying guns, unless you're actively visiting areas where it's advisable to carry a gun, but those are not places you stay for long in, certainly not to live there long-term, more like areas you have to pass through.
