How I look at people who don't seem to understand that just because something exists doesn't mean it's ubiquitous.
I've had to explain to multiple people on multiple occasions why individuals in a post-apocalyptic world would use obsolete weaponry like swords and muskets.

It's much easier to replenish a small supply of ball and powder than it is a sustainable supply of modern ammunition.
IRL people are equally able to be killed by machetes and knives? Why wouldn't people use them in an environment where guns are rare?
