This argument has been made before by Vernor Vinge in his 1999 novel A Deepness In The Sky: civilisations fall due to the sheer complexity they accumulate.
> "They've accepted optimizing pressures for centuries now. Genius and freedom and knowledge of the past have kept them safe, but finally the optimizations have taken them to the point of fragility. The megalopolis moons allowed the richest networking in Human Space, but they are also a choke point. . . ."
> "But we knew-I mean, they knew that. There were always safety margins."
> Namqem was a triumph of distributed automation. And every decade it became a little better. Every decade the flexibility of the governance responded to the pressures to optimize resource allocation, and the margins of safety shrank. The downward spiral was far more subtle than the Dawn Age pessimism of Karl Marx or Han Su, and only vaguely related to the insights of Mancur Olson. The governance did not attempt direct management. Free enterprise and individual planning were much more effective. But if you avoid all the classic traps of corruption and central planning and mad invention, still-"In the end there will be failures. The governance will have to take a direct hand." If you avoided all other threats, the complexity of your own successes would eventually get you.
(note that this is a flashback scene within a larger story; Vinge put into mere footnotes what others would use to write entire novels)
Unless you were in the High Beyond, where you could always escape the collapse by heaping on more complexity. And if you were willing to skip out into the Transcend, you might even become a god. Small consolation to those of us down here in the Slow Zone, though maybe you could stumble upon some leftover computronium and carve murals into it celebrating your anti-libertarian triumphs.
