This is identical to the idea of small scale teams working on systems they completely understand and own. This is where you have the most productive teams and it is the same in terms of bureaucracy. And the job of an architect is not to create "a beautiful system", but to lower the complexity of the overall system.
I think the topic of complexity and large systems is one of the defining ones of our time. Similar to entropy, you start with a low-state system where you can generate energy from putting entropy into the system. But with a higher state of entropy, your energy gains decrease.
We act like you can just pure more and more onto the same pile, but eventually, everything stagnates. And only collapse can create a blank slate.
