And yet, the bigger a software company gets, the more labyrinthine its systems get. Ask any software or IT engineer who was at, say, Amazon, Facebook, or Google, as the company grew from serving a few hundred thousand customers to hundreds of millions of customers.
Similarly, the bigger a country is, the more labyrinthine its systems are (tax, legal, regulatory, etc.). Large distributed systems tend to become very complex, even though no one wants them to be. There are always many competing interests negotiating with each other and reaching compromises that no one likes.
