"You can use any tool wrong - that does not make the tool obsolete."

It's not wrong to virtualize an OS or processes, it's its whole raison d'etre. Also very common see:

https://hub.docker.com/_/debian

https://hub.docker.com/_/postgres

"An explanation how to do the same with docker WOULD fit in a hacker news comment. Sometim, abstractions are useful, even if they add another layer on top of existing stuff (and more dependencies)."

There's so many usecases for docker/( kernel)virtualization that you most certainly cannot fit it in a comment. But I would be entertained if you tried.

Virtualization is as generic and flexible as a programming language, you really can use it to do anything a Turing machine can do.
