You can do lots of things with OWL without a reasoner. The Gene
Ontology is representable in OWL, for example, and uses a simple
enough expressivity that you could do without a reasoner easily
enough. Of course, you need to use some kind of "reasoning" engine,
but something which understands transitive closure is enough. 

Whether it's "easier" to do without OWL depends on what the
alternatives are. You could also represent GO style semantics in RDF
(although, I think, the existential nature of part_of would not be
explicit), or indeed anything else capable of representing a
graph.

When you use enough of the expressivity of OWL, where "enough" is
relatively undefined.
