Optics is what it is. That is to say, the closer you are to the object you wish to observe visually (or photographically), the better resolution is available. The size of the lens matters, too, but there's no getting around diffraction-limited resolution, and satellites will never read newspaper headlines. And they certainly won't read license plates! (And you can't "redirect" a satellite, TV shows like "24" notwithstanding.)
I'm well aware of how they work, and even more about optics. ;)
I'm not saying there isn't better satellite imagery than what is available to the general public, but the fanciful notion that you can capture as much detail from orbit as you can from a airplane is absurd and is a reality that exists only in TV and movies (and paranoid or uncritical minds, I suppose).
I've seen some satellite images that you'd find quite astonishing.
