It is more about being lazy.

In most cases, where you havn’t destroyed your filesystem, you can just boot another Linux from a USB stick, mount your filesystems to /mnt, chroot into it, and then investigate and fix there.

See the Archlinux wiki, even if you do not use Archlinux, it is great: https://wiki.archlinux.org/title/Chroot

No no no! When you break something in Linux systems you fix it. Starting over and reinstalling everything is what you do when you mess up on Windows.
