Of course. Your pat and canned answer does not explain why, armed or not, one would
choose to enter a place that one has judged as particularly dangerous.
So, which is it: places with "no guns" signs are particularly dangerous, and so should be avoided; or they're not?
If someone were to in fact bring his unconcealed rifle into a "No guns" store as you seem to suggest, well, that would at least be honest defiance of the sign--rather than sneaky, secretive defiance--and also, it's consistent with the increased threat assessment that's been suggested.
If I have misunderstood you, and you meant by your words that bringing in a rifle is
exactly what you plan to do on seeing a "no guns sign," well, good for you!
Again, I understand that many prefer to stick with the "I won't disarm for a sign!" line; that's easier to defend than "If I and my gun are not welcome here, I refuse to go elsewhere where they are!"
The examples offered required a minimum of cost to the person to follow. A parallel to the sacrifice of the means to preserve one's life is not necessarily possible, unless we assume them to be similar enough in value.
Two responses. First, an accurate assessment of the "cost" of going unarmed would be the value of the loss incurred (might be life, property, or injury) times the probability of the loss unarmed
minus the probability that the loss would occur even if you were armed (which is not zero). Yes, I know: your life is invaluable to you; for the sake of the calculation, ask your insurance company--they have a different opinion.
Second, again, no one is asking you to go unarmed; they're asking you to walk or drive a few blocks to the similar store without such a sign. Big cost?
A system of ethics can exist in which the value of a decision is not based on the expense to yourself.
I did not suggest that the value was so based. I did suggest that any cost to a given decision will make that less likely to be chosen. I suspect then that situations in which "the right thing" is also the "cheapest thing" result in no need for discussion, or varying opinion; but those which have one "cheapest" solution, and a different "most ethical" solution--now we've got a chance to weigh things carefully. If we want to.
I could care less about what is morally correct.
It is my impression you are not alone.
