The location of satellites is regulated mostly by USA federal agencies. The satelites will also fall back within 2-5 years when abandoned or broken. SpaceX has also obligation to make their satellites 100% demisable with nothing getting to the ground. Besides that you can not see them on the night sky even in rural areas. And they are fully invisible in cities with enormous light pollution. The only time when they are visible to naked eye is right after launch.
