I can't fathom why it's so common to run docker as root instead of as an unprivileged user.

Docker has supported running rootless mode for years. I packaged the docker-rootless into Arch/AUR over 4 years ago, so it's been around and stable that long.

Sure, on a server dedicated to running docker containers, maybe it makes sense for the marginal improvements to network latency. But otherwise, rootless should always be the default.
