Every time I sit in a restauraunt with my honey when he brings up the glories of post-Armageddon earth, I take inventory. How many implements at the table would survive without the infrastructure of civilization? Six million witnesses with experience in door-to-door work, window washing, and convention organizing just couldn't pull it off. As Gopher already pointed out, oil and gasoline would not last long.
Back to the table at the restauraunt. The straw. Would the straw make it? Not without a plastics industry. Plastics is supported by the oil industry. Refineries, millions of miles of piping, truckers, retailers, etc. etc. OK, scratch the plastic straw. How about a paper one? Darn. Need a paper industry first. And a wax factory. And a machine that rolls the paper in to little rolls and makes it waterproof. Not to mention the network of truckers and retailers to get the straw from machine to my hand. OK, scratch a manufactured straw. The women could build each straw by hand. But they still need the paper. Who is going to transport paper to them? Boy, if the women spend all their time building straws, how is everything else gonna get done? Children have idle hands. Let them build the straws. Ooops. Can't do that. I am pretty sure Jehovah is against child labour.
Every time I see a post-armageddon picture, my mind wanders the convoluted path of how in the heck did that get there? Ice cubes, for instance. One needs a freezer, which means electricity and freon or one of the more environmentally acceptable alternatives. Or else they do it like in past and cut out blocks of river ice and store them underground. But those simple cubes of ice would then be worth their weight of gold, more valuable keeping food fresh than chipped for use in a drink. Cutting them up in to cute little cubes would be quite the chore, too. I would expect the adult's hands to be a little more calloused if they had spent the morning chipping ice cubes.
