People do stupid stuff with wiring all the time. Here it's not uncommon to have electrical wires cemented directly into the walls or strung in the space between the outer and inner walls. There's no replacing those without destroying the wall, it's idiotic. Older houses have plastic or metal pipes for running cables, ensuring that you can repair or upgrade the wiring. New house nope, forget it, costs to much.
