In the meantime, to keep themselves safe firearm enthusiasts pay a cost. There is the cost of the firearm, its ammunition, its upkeep and the time it takes to stay proficient. That money and time could be used for exercise to stave off cardiovascular illness, which is orders of magnitude more likely to kill you than a firearm. Those resources could be used for other leisure activities to improve your mental state and lower your blood pressure. Stress-related diseases and stroke are orders of magnitude more likely to affect you than being shot with a firearm.
That's actually a very good point with which I agree, if the costs in time and money were comparable, and I were poor enough that I couldn't have both.
Then I would need to weigh the stakes as well as the odds. Lets say the odds of me dying from a heart attack are very high, lets even say they are 100%, I'll give you that. If I don't spend money on gym membership and instead become a "gun enthusiast", then the odds are 100% I will die of a heart attack anywhere between age 45 and 90. Let's say I am a young woman and the odds of me being murdered are very low, but if it does happen, I get to suffer prolonged torture and rape before I die.
Let's see, what to do? Just how small would the odds need to be before I'd chance the torture session and losing from 25 to 70 years of my life? Okay you make a fair point, I'll grant you that there is some number low enough. But I am also going to have to include the odds of me being in a natural disaster where the thugs from the inner city swarm out like cockroaches and loot my neighborhood. Then you have to add the odds of being in a convenience store when it's robbed, or a bank, or in a mall when the next jihadist goes whacko. And the odds that the neighbor's pack of pit bulls will get loose. And so on.
The odds of any one of these things hurting or killing me is very small, but the cumulative odds of something happening which would make me wish I had a gun, is not so small. Maybe still small, but not infinitesimal, and the stakes of the worst of them are SO very high, that I think on balance I need to take my heart attack. But I don't need to make that choice. I can afford my gun AND get good healthcare, so it's a no brainer. In this case, why wouldn't I want to be ready to defend myself?
