That's a nice metaphor, but it's still not at all certain that Docker is the standard solution. We've had Linux for 20 years and we still don't have a single standard package manager; Docker's been around for 5 years and it's already been abstracted over by systems like Kubernetes, making Docker itself less and less relevant.
What is certain is that systems like Debian and Fedora are not going away. Your Docker images couldn't be built without them, after all. And the other tools mentioned in the article, too, are not going anywhere. So why don't you just standardize on the real underlying platform?
Because there's standardisation beyond just where the app/server/whatever is going to run in production - having a standard way to spin up, describe and control applications & their dependencies that works cross OS lets developers & devops speak the same language, with the same commands.
Is docker the silver bullet for this? No, there's tons of other options. But "everyone should use Debian and Fedora" isn't a realistic standardisation.

But k8s still uses the same concepts used with docker-style 'containers', with registries, layered, isolated filesystem, separate networking, ... all in one box.
Docker was just a big nudge in the direction of democratising scalable cloud infrastructure/application stacks. Yes it can be used for other stuff, but that's what it's extremely good at.
