Actually, even towns and cities can be hurt by erosion. Even if there aren't a ton of water sources, no towns are safe from the effects of rain. Although many buildings are built to be resistant to erosion, rain can form sheetwash, which is a thin layer of fast moving water that can pick up soil and move onto roads or in people's yards. In more severe rainstorms, flooding can begin eroding the roads themselves, especially in places that are already cracked or have potholes.
I am numb to the horrors of erosion. I doubt anything you say could make me feel worse, but what is this soil you speak of?
...soil? Soil is a combination of air or water, organic matter, and broken down minerals as product of weathering.

Just when I thought it couldn't get any worse. How can anyone live knowing such destructive forces exist everywhere.

Well, once you're aware of erosion, you can take steps to protect yourself from it, like building things a safe distance from large sloping hills or rushing water. You could also build buffer zones and use plant life to help keep soil from being washed away as easily.
Hooray! I thought humanity was doomed.

Houses like like this can also be made subject to erosion if the ground supporting the house erodes away, or if a rockslide from the hills forms and collides with the house.
