I think this is maybe a good illustration of the problems you encounter when you go from a highly optimized infrastructure (gas stations) to a “simpler” process (gas cans). If infrastructure breaks down—due to war or disaster etc. - you go down multiple levels at once. Even if you think you understand the process there are likely many relevant details that you may not be aware of that can bite you at any point.
