Another day has come around here since, I've slept over this argument, and I still find it genuinely anti-scientific and smug. As for the coals to Newcastle, did you know that there are steam engines that want to be fed particular types of coal, not any type, to run well (I think I learned that from YouTuber Cruise the Cut)? So there's a point to made that sometimes bringing coals to Newcastle is exactly what you want. Other than that we need much more research in all kinds of cyclic processes that we can utilize to make our activities more sustainable. Right now much too much material is on a one-way trip to the landfill or the incinerator, and how to continue mining and farming is solely left as an exercise to the future reader, with no hind- or foresight, at all. Traditionally people used all kinds of wrappings and containers, many of them suboptimal from a modern POV which we now have replaced with all kinds of plastic which is littering the planet, land and water alike. A solution will not be simple or easy, but if cellulose from grapevine can be part of it, that's probably a good thing.
