Author seems to be mixing up homelab and selfhosting which are 2 different concepts.
Self hosting is hosting services and data you actively use. While I don't seek 99.9999% of availability, this is not where I want to explore and break things on purpose.
Homelab is en environment one use to learn and that is ready to be scratched/broken for the sake of learning. This is definitely not the place where I want to host my personnal services and files (or at least not as primary copy/endpoint).
