No. Just pointing out that a collision in LEO physically cannot create a situation where we’re locked in on Earth for more than a decade or two. The orbits will still have a perigee in LEO. They will still decay. The debris will still burn up eventually. Kessler syndrome is impossible in LEO. And in higher, larger volume orbits, it’s overblown, because we don’t even have enough mass there to create a notable debris field to lock ourselves in with.

A Kessler cascade is one of those things that people read about and it sounds really scary and plausible and happening, like, in a week cause Starlink exists. And that’s where the thought process stops and the Chicken Little everyone has in their brain takes over.

But it won’t be a uniformly higher orbit, because there’s only one event where energy was added to the fragments. The perigee will still be in LEO and anything that’d raise the apogee to a point where the new orbit would be stable for a decade would require so much energy that it’d vaporize the satellite on impact.
