What do you think of all the various -punk settings? Do you use them in you worldbuilding?

What do you guys think about all these various labels? Are they useful, or just kind of over the top? When we start calling all contemporary fiction "nowpunk" it starts getting a bit ridiculous to me, but I also think that "steampunk" is a useful thing that describes a pretty unique and yet common world setting that deserves to have a label.

If you look at this list as a starter, you'll see the following:

  • cyberpunk
  • biopunk
  • nanopunk
  • postcyberpunk
  • steampunk
  • dieselpunk
  • stonepunk
  • clockpunk
  • nowpunk
  • elfpunk
  • mythpunk
  • dreampunk
  • decopunk
  • atompunk
  • cyberprep

I've also seen the following:

  • solarpunk
  • sandalpunk
  • bronzepunk
  • candlepunk
  • castlepunk
  • dungeonpunk
  • plaguepunk
  • middlepunk
  • ironpunk

How much do or don't you use or think of your own worlds in terms of these kinds of labels? What value do they provide to you, if you use them? If you do use them, do you have specific resources you use for inspiration for those various settings and aesthetics?

I've been seeing these terms used more and more frequently, but I don't know that it always helps me understand better, because a lot of the time I have no idea what they mean. There are several on this list that I've heard referenced and tried to google and couldn't find hardly anything about them, so the label then becomes rather useless to me. From things I've read, there's a decent amount of overlap within these, and I don't understand what all the differences and nuances are supposed to be, especially with so little information about so many of them.

For me personally, I just make up whatever setting I'm using and have never really thought about things in terms of these labels. All fantasy and sci-fi stories can be set in whatever kind of world, and don't need a specific label just because you combine a few elements together in a novel way—that's what you're supposed to do as a writer! Am I missing something?
