... and that's a problem. I can't imagine an idea that's worse for space debris than SBSP. It necessarily requires huge masses, and huge surface areas. Total mass in an orbit is what determines if you're past Kessler's "tipping point." Total surface area is what determines how quickly the system erodes into tiny MMOD pieces (each MMOD impact releases 100x as much mass as the impactor itself). The usual lazy rebuttal is that the preferred orbits are currently unpolluted. To that I say, with that attitude how long do you think it will stay that way? The remaining "pristine" orbits are so high up that all the debris generated is effectively eternal.
