the point of SpaceX putting things into LEO (which we should really call SLEO or something, because it's super-low) is that the orbits are self-clearing on a reasonable timescale, months or single-digit years.

GEO is likewise not a problem because things out there are really far apart and they generally don't cross each other's orbits.

MEO (where GNSS services live) is the real danger. Thankfully there aren't a ton of objects there, but deorbiting the dead ones should be a very high priority on anyone's list.

How much money would SpaceX lose per day in that event? I imagine the thread of a cascading set of collisions becomes more likely after the first one, also. I think SpaceX would be very interested in clearing debris as soon as possible in the event of a collision. Months or single-digit years likely would cost SpaceX many billions.
