Theories on Privet Drive Safety Zone

Here are my theories on this idea:

1) The ancient magic used to create the protective zone is not 
something that is done often.  Otherwise LV would be more suspicious 
of its use.  (The fidelius charm is used currently but is not 
apparently something that is used often.  LV could break that without 
the defection of Wormtail.)

2) The "ancient's" methods are no longer in favor for various 
reasons - perhpas they are difficult or require more time than the 
average wizard would want to devote to them.  LV does not seem to 
waste time on anything that does not present him with an advantage.  
Why study all the ancient magic when no one uses more than a portion 
of it?  I *can* derive integrals for calculus but I *don't* do it 
that often and will look them up in a table if I can.  LV would be 
familiar with the existence of the spell but not necessarily with all 
the little details.

3) The zone doesn't prohibit magic being used in it - what if the 
enemy got in and you could use a spell to get rid of him?  Perhaps 
the zone sets off alarm bells whenever magic is used on the premesis -
 that would explain why Harry got all the warnings from the Improper 
Use of Magic people.

4) The zone could function as a barrier to those persons who were 
known (or thought)to be dangerous to Harry.  LV, known DE's, and of 
course the most dangerous Sirius.... well they did think that he was 
guilty and he couldn't/didn't cross that barricade.

5) A safe zone or fort also requires a watchman or in this case a 
watch woman.  Mrs. Figg is most likely the person in charge 
of "holding down the fort".  (No pun intended.)

Let me know what you think.
