Or How to waste a few days copy/pasting configure commands, watching the output of make to be left with a minimal, insecure and unmaintainable system. Only think it will teach you is why distros and package managers exist.
Minimal yes, unmaintainable maybe, but insecure? Really depends on your threat model; courtesy of "minimal", there's not much attack surface to go around.

And more importantly, how a distro works and what a package manager (and package build process) has to do. LFS isn't a terribly practical output for many people, but building it is a good learning experience regardless of if/how you use the built system.
I don't think LFS does that, it's simply page after page of .configure..make..make install. It would be more valuable to read a sysadmin book on unix/linux and play around with a minimal distro.
Just because you don’t see the value, doesn’t mean it has none.
Maybe it’s just me but the instructions seemed to focus too much on what to do and not nearly enough on why. I came out of it thinking that I learned much less than I expected.
In the "good old days" it was recommended to install the linux-howtos package and there was one howto https://tldp.org/HOWTO/From-PowerUp-To-Bash-Prompt-HOWTO.htm... which explained the boot process. There are also other howtos who talk about X.
Nowadays with systemd and the (stupid) tendency of using a lot of shared libraries the things have become more complicated.
