One could make the argument that skipping the bureaucracy catches up with you in the long run.
Or maybe a small team of 10x programmers could really get away with it, indefinitely. But can you reliably staff enough of them, now and forever, to keep that going? For a business it is often better to have a codebase that scales with arbitrarily many average-quality engineers, than to be dependent on hiring miracles. Even small numbers of them.
In other words, the processes themselves place hard upper limits on the possible productivity.
