My whole point is that you can never "truly" lock down a database from a "Malicious" user.
But for a general user, it looks like you have all the bases covered.
;-)
But going back to your original question of turning off the "Options" option.
Again AFAIK, this has always been available.
Why?,
Well if you turned off the "Options", how would you turn them back on to change one?
As I said before, there is really nothing "dangerous/destructive" in the Options.
Basically the just set preferences.
However, things like the option to display the Task Pane, and especially the *Trust Center* are areas of concern.
That all being said, you should always have a "Developer Logon" system to allow you full access.
But to answer your question directly:
AFAIK, you would have to create a custom Ribbon and not include this "option"
Here is a good starting point, you can obviously do a Google search for more info:
