This seems strange to me. Why isn’t it easier to find trees than mine metal out of the ground? Unless we’ve just already mined so much metal it’s easier to melt the old stuff and reform it, but even then that seems like a lot of energy use to melt it all and make sure it’s actually pure or what not
For the same reason that this (and my) broom broke - manufacturers can use an extremely tiny amount of metal and still have a pretty sturdy handle. the problem is that same cheapness means they arent coating the metal well and eventually it rusts from the inside out.
Production cost and waste. Extruding aluminum or steel is extremely cheap going through all the steps to turn a tree into a board into a stave into a cylinder is costly and has pretty steep losses at every step.
