As I said previously, the optical physics, combined with building and launch constraints are what limit us. It is absolutely possible, but it would require an absolutely huge focal length, which means a huge and extremely heavy satellite, which means an extremely costly to build and costlier to launch satellite (I don't even know if anyone in the world has a launch capability to launch a satellite of the size and weight we are talking about). Assuming it is technically feasible to get that kind of resolution from LEO, it's really not a good cost/benefit analysis either when you can put up 1 $20M drone which can give us great resolution and is easy to reprogram, repair, update, etc, vs a $10B satellite that is impractical to repair, operates in much harsher conditions, and offers very little tactical, operational, or strategic advantage over a drone.
