One of the many values of GNU/Linux, and free software in general, is choice. You don’t have to use any particular distro if it doesn’t fit your use case or preferences. I don’t use Gentoo but really appreciate that it exists. If I ever wanted more control over my system, I could turn to this tried and tested distro. I am quite lazy these days and from a short period of breaking Arch, I started breaking Debian, then staying with Debian stable without breaking it and now I have moved to MX Linux, which is Debian that someone else (the MX/Antix team) have set up in the way that I want without having to install everything myself. But, yes. There is great value in Gentoo (like in Kali, Tails, Slackware, Guix, etc).
