You’ve made an analogy about preparedness and let the assumption hang that that makes both things equal.

No. It doesn’t do that at all. Nothing in my comment should be construed as to equate the wearing of seat belts and the carrying of firearms. They are different things, meant for different purposes, with different consequences for their misuse.

The analogy demonstrated ways in which they are the same - having it and not needing it is usually what happens and needing it and not having it can be very bad.
