Disagree. The Iridium phone constellation covers the entire planet (which means it has line of sight to the entire planet) and has for about two decades. Starlink will, soon, as well. They’ve already solved the choreography issue you mentioned.

The entire globe has about 500 billion square meters. 24 bit uncompressed imagery is thus 1.5TB per global image. With some modest compression, you could get a video stream of that from the Starlink network, although the current design of Starlink would make it hard to have room for an aperture with better than, say, 3 meter resolution.
