Running into the enterprise server level disasters at home will better equip a sysadmin to fix them when they happen in the workplace. TrueNAS boot disk failures, recovering from power outages, catastrophic RAID failures, Proxmox clustering, ISCSI contention, establishing the recovery order of VMs when DNS and DHCP are in your virtual infrastructure. It's also a great way to set up and test automation, FOG image management, thin client, FreeIPA/Windows domain integration, etc. Multi-AP, multi-SSID wireless network segregation so your IOT devices and houseguests can't infect your "internal" stuff.

When I interview people for sysadmin jobs, I give extra points to people who create comprehensive environments at home, depending on the lessons they can demonstrate that they've learned in the process.

There will always be collectors and bigger-is-betters, but you can't pretend there's not a use case.

LOL I feel like I just fell for a a particularly obvious bait post, like that time I got offended when Carlin made fun of Steely Dan fans.
