Netmaker guy here, and I'll be the first to tell you that if you have a static setup of, let's say 5 machines or less, then there's no need for something as complex as Netmaker. It's really useful for people who have many machines, or machines that will move around dynamically. Or, if you need to route traffic through a NAT gateway. A static setup is fine for technical people and small networks, it's just not scalable. As an analogy, you wouldn't run Kubernetes if you just need to deploy 3 docker containers, but as the complexity grows, you need a management system.
