I want an impenetrable wall of space junk to protect me from meteors. We’ll deflect those nasty comets and meteors right back into space and enjoy high speed internet as a bonus.
I realize that you are being sarcastic, but the earth has a surface area of 196,936,994 mi², each satellite will have and average of 4,700 sq/mi to roam in. But in reality it will be much less as the satellites are clustered over the more heavily populated areas, and far fewer over empty oceans and deserts.
