On the topic of burning down buildings to get nails. My grandfather would never through anything away at his business whether it was good or not, he always had this reasoning, that it was still good to someone. He basically built and started his business on buying, sorting and selling, excess lots of products from ww2, Vietnam, business closures, etc. Seems like quite a few people I've met from older generations have a hard time throwing stuff out. It's weird to think of a time when items we're so hard to come by.
