Getting back to the point:
You literally claimed that one of these would "inevitabl[y]" trigger a Kessler effect with no proof.
> something literally 1000x bigger be even more concerning.
Again, this isn't convincing if you don't have the denominator/context. Think about it: you still can't answer how many of these are needed to trigger the Kessler effect.
BTW, "increase by a FACTOR of about 300" != "increase in a RISK FACTOR of over 300"
