you mean, docker? Everything you can do in docker, you can do with jails.
Jails can have Virtual Networks with their own interfaces, you can resource limit, host virtual machines and setup nested jails. As well run the Linux kernel. What more could you want?

Jails provide the same sort of primitive as cgroups et al wrapped up into the concept of an OCI container, yes. But lack the entire ecosystem of tooling and services that go around those.
Saying jails are a meaningful alternative to containers completely misses most of the ways in which people actually _use_ containers. The experience as-is is closer to a lightweight VM or LXC than what people associate with containers.
I say this as the kind of stubborn person that invested the time to spin up a cluster of FreeBSD machines running Hashicorp's nomad as a task orchestrator to manage running jails published to my "repository" across the cluster and recreate the general "container" experience. So my experience may be out-of-date, but this isn't from a place of ignorance or lack of love for FreeBSD, but from a place of "I've managed a colossal pile of bash scripts to recreate the container experience with jails and, no, for the average person it's not fair to call it the same thing.".

He means he wants to run FreeBSD inside the container environment, not as the host OS.
No, I'm talking about running FreeBSD on the metal and then running containers without a Linux VM to as the host for containerization.
The container environment has to sit on a kernel. Whether that being Linux or BSD; BSD has shown support where *nix has not.
