That's not a desktop setup. It's much more complicated than the workstation setup I use at work. A desktop setup is my Xiaomi laptop with Ubuntu 18.04 that I use as media caster or to browse amazon while on the couch. It works flawlessly, much better than the preinstalled Windows 10 in chinese.
It certainly is a 'desktop', it might not be yours but it bears resemblance to mine. The 'desktop' metaphor might have been equated with complicated all-integrated environments like Windows, MacOS, Gnome and KDE but in the end it comes down on something-on-a-computer which provides a place to work and access to the resources the computer has to offer. Like physical desktops these come in al shapes and sizes ranging from an empty slab with a lamp and not much more to ornate baroque monstrosities with a zillion drawers, Rolodexes, mail-in-out-boxes, staple machines, paper dispensers, coffee machines, vortex portals and flux capacitors.
Some ascribe to the diction that 'perfection is reached when there is nothing left to take away', depending on your starting point you either end up with a lightweight environment like Xmonad (et al) plus a few tools or at a lobotomised full desktop like Gnome.
