This is a pretty interesting perspective because my experience of using Arch for a decade is that the Arch forums are a great treasure trove of learning how to troubleshoot a Linux desktop. I also have never seen any prescribed advice of reinstalling from scratch and rather the recommended approach is booting a live image and chrooting into your system to actually fix what's broken when something truly is borked. This is also why there's such a hefty RTFM culture around the distro and avoiding going through the install without actually understanding what you're doing.

Arch has been the most stable desktop system I've ever used, but a lot of that stability comes from understanding exactly what is installed and configured, which is something I personally never got with Ubuntu or other fully configured distros
