It's fully possible to make a generated script that makes a path with a good useage of multiple dirt tiles, and also have some random changes in the path (to give it that natural feel or whatever)

Mostly anything you can tile out, can be done with a generator.. simply because the generator is tiling the same tiles you are. It's not like laying down predefined objects.. the generated scripts can be made to do random things, set down random tile patterns, etc. So what is the difference you say? Well, doing it by hand, you generate the pattern from your mind, doing it by the generated npc, it generates the pattern with a random calculation. Your mind is randomly calculating which tile you want to set down, so I don't really see a difference when it comes to this.
