> there's a certain amount of natural space debris surrounding planet earth. This amount has reached a steady state over the past few millions or billions of years. For what it is worth, I would question this assumption. Why would the amount of natural space debris around earth be at a steady state? Meteor showers [1] are one example of how the amount of space debris is not at a steady state.
