I must side with Google on taking pictures of every street in the world for the following reasons:
- Tourism will boom when we can see everything. Planning trips becomes easier because you know exactly what the place you are going to looks like.
- We have had satellite imagery for the entire world for decades. Street view cameras blur names, faces (which is so effective it even blurs signs of faces), and numbers, protecting privacy, and when there is offensive imagery the image is either not put on or promptly removed.
