File systems are databases of some sort: there's a way of storing and retrieving data. Using the FS won't necessarily be simpler or less resource-intensive than using sqlite or something similar, because you _will_ store and retrieve data, and the helper layers you build on top of the FS will probably be less optimized than existing lightweight databases.
