If we aren't careful with space debris [1], deorbit protocols [2], and anti-satellite weapons [3], we risk triggering a Kessler syndrome [4] and permanently blocking our access to space. We currently have no international space agreements outside of not putting nuclear weapons in space, which is wholly inadequate for managing the dangers and safety of space development.

The only reason space has been managed decently well until now is because most of it was done through the US and Europe that have very strict regulations around safety. Don't expect this good behaviour to continue.

That's a very ahistoric narrative. There's been *zero* regulation around space debris in either the US or Europe, for almost the entire space era up until now—most of it isn't in effect yet. Far from being "strictly regulated", US space operates recklessly with regards to space debris. One ongoing example: spent (ULA) Centaur upper stages have exploded in orbit in four separate incidents since 2018, due to ULA's negligence in correctly passivating/deenergizing them. Which they were never obligated to do anyway—not by regulation,

The reality is that space debris is a less consequential problem than you'd get from reading HN; the early players in space could, and did, get away with being extraordinarily negligent.

Meh, orbits and nuclei are vastly different scales, I've tried to simulate this by making everything in space-track a 10km radius sphere and it was just a few starlink nudging each other a couple times a week.

I don't agree. Kessler syndrome is another M.A.D. scenario. Nobody would want it to poison the well for everyone incl. themselves.

Kessler syndrome is incredibly overrated.

It's completely incapable of "permanently blocking access to space". What it's capable of is "shit up specific orbit groups so that you can't loiter in them for years unless you accept a significant collision risk".

Notably, the low end of LEO is exempt, because the atmosphere just eats space debris there. And things like missions to Moon or Mars are largely unaffected - because they have no reason to spend years in affected orbits.
