Because it is generally a very bad idea to try your own DDL or DML on data dictionary.
Maybe Oracle should have had prohibited that sheer possibility in the first place.
It would be re-inventing the wheel, and it is very unlikely that you can setup something *faster*
than Oracles built-in functionalities.
Or are You such an incredible guru that you are aware of all possible side effects ?
Your questions indicates that you are not. I could think of only a very few persons who are - excluding myself.

It is better to find out what is already there to be useful, and only if You are *very* sure
that there is nothing for You (which is very unprobably), then one might start thinking another way.
Unfortunately there is too much "I donīt know. Pity" := "Itīs not there. Dammit" all over the place.

So, using auditing is the best way. And You may *use* v$-views to setup your own auditing,
but *without* changing the DD itself.
