I am drifting to another territory such as what would the one thing be if I could have only one item produced by civilization. A blanket? A fishing line? A lighter? A crowbar?
As a technology and sci-fi lover I questioning myself why people tend to chose items invented hundreds of years ago like knife, bow, blanket. I am always thinking - a cybertruck, Water Desalinator and cleaner, high tech body suit aka iron-man suit :D
Affordable, easy-to-find, light and easy to carry, basic-need-taking-care-of, etc.?
