Single family houses I can understand how it could work. But what would happen with any multi-family/multi-apartment building? Only one of the owners (or a renter) can blur the whole building (or only the parts corresponding to his/her windows)? And how can google tell if the request comes from someone actually authorized to ask for the blurring? Seemingly anyone can blur any home, and even if the request is cross checked with IP geolocation (usually it is not very accurate AFAIK) that would be possible in the same city/neighbourhood.
