You raise several interesting points. Assuming your AV has done a thorough scan of your hard drive and found it clean, assuming you check daily for new definitions, and assuming you have your AV running at all times, then a daily scan of your computer is not really necessary.
Most people do scans periodically in safe mode, for the simple reason that some viruses like to esconce themselves in areas Windows protects while using them. Safe mode will prevent those application accesses, and hence unprotect the viruses.
Whereof one cannot speak, thereof one should be silent.
