The goal isn't "ease of deployment", the goal is "infrastructure as code" so that application infrastructure can be managed in a way similar to application source code (e.g. PRs, blame, code reviews, CI, rollbacks etc). This helps ops people because it allows them to think about infrastructure as abstract resources rather than as a collection of individual machines with specific designations. With k8s, individual machines become a homogenized resource that do not need specialized provisioning depending on the application they will host.
