I am not an archaeologist, but I thougt I understood the gist, just from the title. And after reading the article, there was little light shed. A couple of points of context. - urban archaelogists in Britain find a very bright line between pre-tobacco and tobacco. Once in that latter period C1650, they are immediately inundated with disposable clay pipes. Lasting a couple of centuries. But the physical nature of those pipes provides little extra information. Nobody documented their manufacture. - Its a kind of inside joke that our contemporary civilisation will deliver a similar quandry to future archaelogists: presumably, the archaelogists of the title. That is: there will be a similar bright line between pre-1980s ring-pull which were distributed absolutely everywhere, then immediately not at all in our contemporaneously developed world. So I assume this was written for future archaelogists to get better context on contemporary detritus.
