Kessler is inevitable. Today, no one will cancel satellite launch because others asked them not to. Since humanity is not capable of cooperating we will end up with satellites Cold War. We actually in it already. I’d rather let them learn the hard way and make them all crash, than use it for military advantage. Yeah, some satellites are useful like wildfire monitoring and GNSS, others are either flex or military. Maybe loosing all those useful one will make humanity cooperate and lunch only what really necessary in coordinated and transparent way
