That's doubtful, Mark. That wasn't my argument.
People tend to litter regardless of whether the property is publicly or privately held.
The enforcement is the real issue. I think you are confusing liability risk of who pays and how much if something falls off or explodes in orbit, verses the technical risks mitigating the likelyhood of it happening or the magnitude of the resulting hazard. Changing the current liability regulations to something closer to maritime liability would be positive force in stimulating commercial space develompent. Actually private insurance against debris hazard is currently a strong motivator for minimizing debris hazard. A heavy handed government driven crackdown on orbital debris would have a chilling effect on the commercial space industry tending to drive insurance rates up rather than down.
