Oh, you were focusing on the explicit notion of virtualizing IPs. I thought you were pointing out that Kubernetes itself is not the one generating the IPs, since it's the CNIs that do so, which are not built-in... Either way, we are in agreement I believe. Kubernetes mandates for CNIs that they must allocate unique IPs, but they do so through a variety of mechanisms, sometimes even using external infrastructure.
