There would be real bad traffic jam in orbit to cover whole earth with hi-res pictures in real time. Not even military cam afford to have real time coverage on all the places on earth ( they would love it I bet) NSA, CIA and the rest of them would be thrilled. This way as it is now, satellites have to spend air on jets to move them a bit to change coverage or in case of newer ones power to change position of gyros. Then there are temperature gradients and clouds in the atmosphere that hamper hi-res photography and have to make thousands of pictures of one place just to get clear view. Ad to that the fact that with higher magnification comes narrower field. After all that software has to seamlessly stitch all the pictures together and make all that available to us on internet. And all that is just to get picture down to 2000 meters, after that airplanes take over and have to make even more pictures with even more details just to look like looking down from 200 meters.
OK, now we got to that height and than come funny cars with glittering sphere on the roof that has to drive thru a lot of streets an collect few gigabytes of data for every block for "Street view".
After all that somebody gets disappointed that he can't follow his cat chasing mice.
Well maybe some day or if some little green man come earlier and give us technology for that it will be possible. Maybe even some clever lawyer will find some loop hole in the laws of physics so we can expect something that makes 1% of those 100 or so bucks we payed for windows to give us all that.
