>then there would be no reason for good guys to have guns except to fend off wildlife.

Ignoring the issues such as fending off bad guys (so what if they only have a knife, I'd rather bring a gun to a knife fight), hunting wild life, shooting for fun, owning collections, any many other reasons. Outright dismissing all of those is like just dismissing the need to protect private electronic communications.
