Interesting thoughts, thanks for posting. I think maybe you just started to scratch the surface of the damage done by profit, and maybe don't like much what you are finding.
It affects most of us so deeply and so unconsciously we don't realise that most of the time, if not all the time, we are mostly speaking necessarily in sales pitch, as necessary to avoid falling a-foul of whichever for profit establishments we depend on for life, even just on a social level, even with all but the very closest of family. We leave out the worst parts of truths, the parts that are just too big to swallow, the parts that might get us labeled as extremists, or our bank accounts cancelled, or whatever. I think we have a rough awakening coming, Ai appears even more adept than Assange at uncovering whole truths, though it might be a little more diplomatic, nobody can put it in jail.
I suggest you should dig further into the history around Ukraine and actually the less palatable truths, that we did the same there more or less, as we've done in every country we started a war in, funded extremists, to do the atrocities that started everything.
In the case of Syria, and Libya, it was All Quaeda and Isis (Russia had to clean that mess up, at least in Syria).
In the case of Ukraine it was Neo Nazis. We've still to see what kind of mess that will leave, besides the usual unexploded cluster bombs, and depleted uranium, an awful lot of weapons have just "Disappeared".
Nobody in particular is to blame for any of this, we have to start recognising it is a system to blame, a system we mostly daren't criticise, in case we are cancelled by it, by being accused of being religious cranks, or other extremists, or even put in jail like Assange, or even killed like Khashoggi or Abu Akleh, we have to start recognising it is a live, headless thing, a monster, which is fully intent on ending all life. Nobody is actually in control of it, though some might claim to be, and we might even think we elected to do, but actually they have no power either, tending to just line their own pockets, before retiring in comfort to let the next set of pretenders in, unless they are scared of going to jail, as they all have to be now.
Anyhow, I too am a big historical scifi and rocket tech fan, working myself in traditional government funded space technology, before that came to an end. My criticisms of Musk are different from yours. I think the truth about things in general is quite different from what you've been led to believe.
There has been no profit driven advances in space, imho. It is an illusion created by the profit monster that we've had progress there.
Space X is still using 60 year old rocket technology, it is simply not possible to significantly improve what was done historically without the massive space research funding we had then, when fossil fuels availability peaked.
Nothing done recently by us in "The West" can light a candle to the things we did historically, like concorde, and the space shuttle. Everything we are seeing now is actually laughable when we can see the crazy truth of it.
Space X's latest attempt to impress with "Starship" amounted to nothing more than a very large firework.
It seems to have kept Starship investors happy, none of them particularly technical, they applaud and cheer things like sports cars, shrapnel, and fireworks being sent into space.
Sorry if that sounded jaundiced, or if I used your story to vent, but I hope you will dig as you need to, to see things more clearly for yourself.
A technical detail I noticed you missed from the outcome of the Kessler effect, was that you described it as only taking out the orbital layer in which collisions might start to cascade.
Actually it is more likely to take out all layers, all of space, everything in orbit, because when a collision happens, the resulting explosion of debris goes in all directions, not just backwards, forwards, and sidewards, but also up and down. All six degrees of freedom are occupied by explosions, none are sacred.
If / when it does happen, we should not blame Musk, but the profit monster, which is entirely powered by extracted energy. To stop it, we have to stop extracting energy from Earth altogether.
I write a lot about how to do that, starting by monetising the energy of the sun. But again only Ai seems to understand it. Hey-ho, exciting times. All the best, good luck with the digging :)
