The trouble is that those of us who know all of this have no power to do anything about it, no energy in the form of money to fund any real opposition or authority.
At its heart, the reason is because of profit, which is an energy con done on the planet, and this unfortunately has become the main funding source for all of science.
Science has never been in a position to examine itself, enough to identify and trace out the overall effects of profit on all things, including itself, it seems to me, as someone who has been pursuing that now for seven years self funded and counting, since first seeing it coming around 2017 whilst on PhD candidate research.
I call it the global energy problem. it's existential, if we can't sort it out.
Like you say a kessler process could turn out to be a catalyst for an unstoppable chain of events leading to our rapid demise, since everything is stretched taught to near breaking point, all supply chains, all lines of communication, all means of utilities power generation, all means of transportation, actually just about everything we can imagine.
But look, all those other things stretched taught are themselves each all vital links in the chain of civilisation, as well as many more not identified here, we have to include world peace, since the alternative would be unsurvivable nuclear, and climate disaster due to global warming.
Any of them breaking would result in the whole chain of life sustenance breaking.
The thing stretching it ever more taught is availability of energy to extract - this is reducing all the time, since it peaked around the seventies, and since profit is directly dependent on that, profit itself is becoming more and more difficult, and we see that with ever increasing numbers of companies now going bankrupt, with the direct result of ever more people becoming bankrupt and homeless etc.
Its all down to profit, which results in a system of energy slavery, in which no single one of us has any choice but to participate in, even the richest, and since profit is directly related also with temperature rise, profit being actually a measure of destruction, and hence the temperature in terms of thermodynamics, we should realise we are hitting a critical point in our existence, where if we can't change, we will come undone, impacting all of life with a sudden chain of unexpected events.
Its a systemic buildup that really needs the application of formal systems Engineering tools and techniques to analyse and trace through with any confidence.
This has been my trade for most of my working career, and have used now to analyse the full stakeholder model including sun, Earth, and nature as primary stakeholders, and there is dictated from that, a single solution, which is to switch from using the energy of Earth, to using only the energy off the sun.
Hydrogen is key in the solution, the "inefficiencies" of it, when generated by electrolysis from solar become irrelevant, what matters is the effect of the energy stored, which has to subtract from the natural accumulated heating effect of the energy of the sun.
We would be naturally inclined to create and store much more hydrogen than we need at each generation / backup point, on a domestic and community distributed solar energy basis, per our instincts to do this by the free energy principle, and this would have the effect of winding the temperature back down by what would be a reversal of the process done by our consumption of fossil fuels to date.
Because we would be creating instead of destroying.
To have it, we need to insert our own deliberate catalyst, before any other catalysts occur.
Commencement of issue of solar indexed stimulus is what is required.
This will fund and incentivise all to complete the switch to all solar.
Sorry long post, it's a complex system, with complex solution also involving now Ai, since that looks required to control everything.
I write much more about it in my own stories, but a quick portable summary is in my Amazon e-book, "The Energy Polarity Multiplier Framework".
That book becoming popular at all, perhaps by being recommended by credible scientific reveiwers, would be incredibly good news, not just for me, we would be well on the way to collective understanding, which is surely required.
