-You can't eat them.
I grew up hunting. I can kill game. However, in a post-apocalypse world I would do more trapping and fishing and save the ammunition.
-You can't drink them.
I can brew beer and make wine. Who wants to drink a weapon?
-They can't power your well, sump pump, freezer, or furnace
No, neither can a roof over your head, but that doesn't mean I would live in the open.
-A gun doesn't do a very good job of providing you information about the weather, news updates from the CDC, or other emergency management information.
No that is why I have an emergency radio. See my answer above.
-1000 rounds of ammunition == approximately 1000 dead zombies +/- your accuracy. This becomes a problem when the zombie population goes > 1000 zombies. A delta of zombies is a bad thing.
I have reloading equipment. Also I do know how to make gunpowder from sulfur, charcoal, and saltpeter, but god forbid it comes to that.
-Guns cannot process large game into juicy delicious steaks all by themselves.
No but I can! See my answer to number one above.
A lot of what you are saying is the equivalent of "A boat is not a car, so why would I want a boat?" My answer is when you NEED it you will WANT it.
