Based on the way the desert monks file is setup, I would guess that the artist (like many digital artists) is used to designing for digital delivery, or digital print, and not for machine use. There are lots of layered elements that have not been trimmed down, so while they look good onscreen there are a multitude of hidden, overlapping toolpaths that would cause issues if sent to the glowforge, or to a vinyl cutter.
Each cactus, for example, is a separate element from the shadow below it, and those shadows are actually 3-4 individual elements each as well. Those each need to be united into single elements. The gradient layers extend into (behind) the mountains, as does the moon.
Rasterizing would save the hassle of all the vector work, but a clean vector version would allow to do more with it… a two-layer piece, with the engraved desert behind the monk/circle/name would look pretty cool!
