Yes, we probably are.
While I don't think firearms are magical talismans that ward off criminals and crime, I do think they are a tool that people who have objectively good values have or want to have. I think laws reflect that too... Castle Doctrine vs. expectation to retreat, for example. A society that controls/bans guns is effectively revoking a natural right to self defense. That makes it easy for criminals. And the easier it gets, the less of a check on their behavior we have.
So fewer guns = less opportunity to balance crime = more crime
Not because the guns are magical metal but because they are tools in the hands of decent people. Decent people can't practice their values witout tools anymore than a construction worker can build a house without his tools.
I also think it's more than a hobby for this reason and why it's a Constitutionally protected right.
