I have tended to think that people underestimate the vastness of orbital space, and that

Certainly an argument for staying low enough at first to allow atmospheric drag to clean things up.
At least for the first several years, AI hardware will advance fast enough that an orbital lifetime of ~5 years is fine.
Note: once you get far enough into space, it’s just so absurdly vast that “Kessler Syndrome” can’t happen due to extreme sparsity.
