I see what you’re saying, although being turned into glass also has deleterious effects on the infrastructure. Being in Mad Max would suck. But the reason I’m not nearly as worried about them is that they require an evildoer to have impossible motives. If MAD ever fails, it’ll be because somebody was genuinely trying to wipe us off the map, not because they wanted to cause widespread but in many cases survivable hardship.
Now, the little ones might be quite fucking annoying or even indirectly deadly if you set one off in Times Square, or the basement of a hospital, and so forth. Again, I’m not saying you’re wrong to be freaked out by them. But you’re not wrong to be freaked out by a $500 bomb, either, which could also be assembled from readily available stuff by non-experts to bring a hospital down in a different way.
