What’s the goal? If the act of _building_ a homelab is the fun then i agree 100%. If _having_ a reliable homelab that the family can enjoy is the goal, then this doesn’t matter.
For me personally, my focus is on “shipping” something reliable with little fuss. Most of my homelab skills don’t translate to my day job anyway. My homelab has a few docker compose stacks, whereas at work we have an internal platform team that lets me easily deploy a service on K8s. The only overlap here is docker lol. Manually tinkering with ports and firewall rules, using sqlite, backups with rsync, etc…all irrelevant if you’re working with AWS from 9-5.
I guess I’m just pointing out that some people want to build it and move on.
I'll agree to disagree on it not being applicable. Having fundamental knowledge on topics like networking thru homelabbing have helped me develop my understanding from the ground up. It helps in ways that are not always obvious. But if your goal is purely to be better at your job at work, it is not the most efficient path.
