one thing I like about my brain is how if i'm interested in or thinking about multiple subjects at once, I inevitably end up synthesizing them all into a new idea even if it doesn't immediately make sense to put them together
I'm thinking about this backrooms vid and also thinking about lawns, American urban planning, and Minecraft.
My preferred take on the Backrooms is that it's a compelling concept when (and because) the place itself is the monster. The core of the idea's interest, to me, is imagining a (seemingly) "man-made" environment that is indifferent and arbitrary in the same way a geological formation or a cave system is indifferent and arbitrary. 
This place looks like a building, but there is no trace of purpose behind its structure and composition. This place isn't designed to be used or lived in by humans. It's not for people. It's not for anything. It inevitably doesn't provide for human needs or accommodate human life, and that's why the Backrooms is scary—it's as purposeless and "un-designed" as a wilderness, but the lifeless nature of such man-made structures makes it desolate and deadly.
It is a lot similar to the way the procedural generation of structures in Minecraft often creates buildings that seem bizarre and useless in their layout.
"Almost unmistakably man-made object or place with elements of illogic and randomness that increasingly rule out the possibility that actual humans built it on purpose" is a great concept in horror.
I think it is linked to a real characteristic of many (particularly American) man-made places. The contemporary world is increasingly full of places that are not "for" humans or human needs. A building communicates messages to us. A building has a purpose; it is used to fulfill a human need in some way. The design of a building reflects what it is "for." Architecture can, like anything, be a form of art that is more aesthetic than practical, but this is still a purpose.
And as we are surrounded by structures whose purpose is more and more abstract and disconnected from the needs of humans—commercial buildings that exist to generate profits, vast parking lots that exist to hold cars, concrete courtyards that exist to take up space, lawns that exist to make a house look well-maintained, dead malls that are being maintained despite the absence of usefulness and relevance—the idea of the Backrooms becomes more resonant.
The ultimate example of this is "hostile" anti-homeless architecture in cities. These structures make it clear that a place is not for humans.
"Purposeless structures" in horror, apart from being deliciously uncanny, highlight the way contemporary landscapes are designed to separate us from the things we need for our survival, not to provide those things—and at best aren't designed with meeting human needs in mind at all.
