There are theoretical limits imposed by Dawes' limit. For example lets say you want to read a license plate, which you could do with some fuzzy ability at 1cm.

The Amazon Kuiper satellites orbit at 367km which means they would need a 20m mirror to resolve this much. Needless to say these would be enormous and probably physically impossible at that height.
