For me it is the same issue I have with portals, food. Farms are not easily relocated (or, do I really want to set up a farm here for the short time I will be getting materials here?). Boars for sausage are either in Meadows or a boar farm I have set up, both possibly a long way away from my current material farming location. The difference is, with portals I can get back to Meadows/Farm/Etc very quick to restock food items (and later meads). Not so much without them.
