Well, let’s look at the stealing case, then. You don’t consider anything wrong with taking my stuff, since you don’t believe in private property. Fine. You also don’t believe there is anything wrong, as we know, with sticking guns in people’s faces, so why object when I defend my fictious property? If it helps, I’ll get some cardboard and aluminum foil and make myself a piece of costume jewelry to wear while defending my property.
We have a trade-off here. The situation can be ‘completely solved’ as you say, by shooting anyone who produces a candy bar without a label. I say it can also be ‘completely solved’ by you not eating a candy bar not labeled as safe for you. In one case, I get a gun in my face. In the other, you can’t eat a specific candy bar. On what basis do you favor one over the other? I’ll read on and see.
Ah, it is degrading to…what exactly? It’s already the case, no matter what, that the allergy sufferer cannot eat every candy bar available, and can only eat specific candy bars. I suggest that he refrain from eating bars not labeled as safe, and you suggest that, well, I suppose every candy bar wrapper has to list every ingredient, not just in the bar, but used in the factory, and you claim it is degrading to have to refrain from eating some candy bars that do not contain the allergen. At least, that’s the best I can do at reconstructing just what is degrading here. You apparently don’t think it is degrading to have people walking around threatening to shoot you if you don’t produce a wrapper up to their specifications, and don’t think such a situation could possibly lead to any fraudulent outcomes. After all, empowering a large agency to carry this out, with no market competition, cannot lead to some unscrupulous producers paying off inspectors, right, either to shut down their competition or let them get away with things. Ok, so suppose that is not at all degrading. So now this supposed degradation of having to look for peanut-safe candy bars justifies shooting candy bar producers why exactly?
Once again, suppose I didn’t make any candy bars. Then I wouldn’t incur your wrath here, but I also wouldn’t produce the very tasty morsel that you consider it degrading to not be able to eat. So it’s ok to deny to the entire world this tasty treat, but not to only you?
Now, what if there isn’t such a market? Then there was even less reason for you to be shooting me in the first place. The lack of a market for peanut-safe bars suggests that I’m certainly not going to go to any effort to have a peanut-safe factory in the first place, and you haven’t (yet) proposed forcing people to open such factories, so in that case, there just isn’t going to be a candy bar you can eat. Degrading, I know.
As for your irresponsible kid who eats a candy bar not labeled as safe, I have no reason to believe he’d do anything different if we required the manufacturer to list every item used in his factory. Why do I say that? Well, first, I used to work as a paramedic, then as an EMS chief. I worked a large number of calls where people with allergies ate items containing allergens, and it so happens that in our world, we follow your idea. Subway had a big sign listing the allergens in their low-carb wraps, yet I treated many patients who ate them anyway. Second - your scenario leads me to think it. You posited a world in which a food cannot be deemed safe for allergy sufferers unless it is so labeled. The kid you’re talking about picked up a bar not so labeled - i.e. one which he had been taught not to eat - and ate it. Why won’t he eat the labeled bar too?
As for your last paragraph, you’re talking in generalities, I’m talking about a specific case. Is it or is it not aggressive to shoot candy bar makers?
