In some situations, yes, others no. For instance if you want to control memory or cpu using a container makes sense (unless you want to use cgroups directly). Also if running Kubernetes a container is needed.

You have to differentiate container images, and "runtime" containers. You can have the former without the latter, and vice versa. They are entirely orthogonal things.

E.g. systemd exposes a lot of resource control as well as sandboxing options, to the point that I would argue that systemd services can be very similar to "traditional" runtime containers, without any image involved.
