If the answer is binary, there is no need for a "Why", right (the answer is rhetorical)?

Multiplexing your control files and redo files is not required in a normal database, therefore it wouldn't be required in a DG configuration.

However, with a dataguard solution, you have a possibility of missing a small number of transactions that might have been logged in your redo logs, but haven't been archvied yet. Even if it has been archived, the archive might not have gotten over to the standby database yet. Is this an acceptable loss to you?
