Only if you have to. Not all processors come with a MMU. Using an OS is not always necessary. There are size thresholds for which a MMU makes sense - so memory management does not always imply a memory hierarchy which requires a MMU. Maybe a MMU does not make sense in systems with deterministic & hard real-time requirements.
