Do the extra sails even do anything arrayed like that?
See the artist's commentary. It's not a sail, it's a barrier designed to snag bits of orbital debris. (I'm not saying this is a useful or practical solution, just that it's what the artist intended it to be.)
I feel like a whipple shield made of nextel is just going to create more debris or be ineffective considering that even paint chips can cause impact craters the look like bullet holes.
