Space is so massive that if you were to take the orbital diameter of Earth/Moon and deconstruct all the resources within, and turn into a mini Dyson sphere with an internal atmosphere, the internal surface area of this shell, would be large enough to support 100 trillion trillion people each with space equivalent of a small farm and still have enough space left to question "what do we do with the rest?“

By the same token, surface area of Earth's orbital plane is so huge, that the probability of a satellite collision is crazy low. It only goes up when you have state actors firing ASATs at existing hardware and creating hyper velocity debris fields.
