Once the most important thing on your system has been compromised, reinstalling is the last of your problems.
So why bother with UAC at all? Why don't we just go back to a crappy single-user version of Windows and be done with it?
Yes, a user's data is the most valuable thing on the machine (to that user) but allowing the OS to be deeply compromised enables malware to do things other than just compromise the data on the machine and the end result may be far more harmful.
