While interchangeable, standardized parts are significant, they are unnecessary if we make and repair our own stuff out of materials sourced from the land and water, and said stuff includes: canoes, paddles, baskets, bedding, shelter (even large houses for several families), hand tools (including weapons), and clothing, off the top. These "old ways" will keep us going on Earth awhile yet, and not just scudding along the bottom, but thriving, together.
