I did a back of the napkin calculation a while ago regarding how many car lengths you’d need to put in LEO to have an unbroken traffic jam in orbit and the result was surprisingly comparable to the number of cars we’re currently producing. If you were “simply” launching wire instead I’m sure you could get enough material up there in much fewer launches. I’m curious as to how you would construct such a loop since you’d need to station keep it somehow while it’s inoperable.
