So yeah, what you're missing is that there are natural monopolies. One such would be a centralized tax collector for a nation state. Some others would be a centralized copyright, patent, vehicle or real estate registrar. In terms of software it helps to have a centralized repository for code as this eases development quite a bit. Imagine you need libraries from multiple repositories. That's a pretty big pain point. Eventually everyone will migrate to just a single source. Again, these are natural monopolies and primarily driven by the network effect.
