I mean, you can technically do all that without the need for docker or even any
kind of complex setup at all. Docker doesn't actually bring anything new there,
just more complexity in order to achieve it really.

This part, in more recent times anyway, is true, however... There are going to
be some unique differences in even that, which is partly a problem. Containers
definitely have some universal aspects they can do, and then they also have
some that will be hardware/OS different which can (and will) cause issues in
certain situations.
