 Despite its popularity, this is not a very good reason to believe in compositionality. The fact that compositional semantic theories can explain certain things does not show that they explain those things because they are compositional. Do we have reason to think that without assuming compositionality we would not be able to explain the same things? It seems to me that we have no such reason: semanticists have focused on whether they can hold on to compositionality while providing satisfactory explanations, not on whether they have to embrace compositionality in order to provide satisfactory explanations. We are not entitled to assume that adopting compositionality as a working hypothesis has in any way contributed to explanatory success in semantics.
