It might be reasonable to protect Mr. Obama's house image. But why not protect commoners' houses equally?

He and his family are under Secret Service protection for life, so they are not like commoners already, so it makes sense that their houses have special treatment.

On the other hand a motivated party can easily get a satellite view from Apple Maps / Google Earth or even build a 3D map using a drone (it is not a no-fly zone). So it doesn’t really contribute to VIP’s security.

Same reason real bank has more security than piggybank.
