From my personal experience the problem of already having a working display right in front of you but it being no longer (reasonable) to use.
You can set up something like mouse without borders or something that uses it as a over the network display or buy these controllers and make a custom case/mount/stand but in the end you're probably better off accepting you're better off buying a new monitor even though this one works great you "just" need to detach it from the laptop.
For as many that say "but I did and it works great" you don't really see many people going out of their way to get a laptop screen instead of a monitor prior to the cost already being sunk. That being said sometimes it's useful when you explicitly set out to build a budget custom video wall (11520x6480 52" can be had for cheaper than one might imagine) but usually you're buying specific panels at that point not finding yourself in possession of 9 of the same model laptop display by accident.
I don't see people going out of their way either. I know it's not explicitly stated, but there's a bit of a subtext of getting something for nothing in these articles about turning laptop screens into monitors. I can see the appeal of $50 + something you already own becomes a small high DPI monitor. For me personally, and for what I assume is the majority of the contributors to HN, I see the computers in front of me as a distributed system, each with different capabilities. To dumb it down to two or three screens attached to one computer is a downgrade from the cross-platform multi-screen environment I can build if each of these screens is attached to its own computer.
