Not sure why you're bringing land based solutions to the conversation with "it's been done many times". If that's the case Webb has been done many times and is

  The physics of stacking detectors doesn't depend on space vs. land. 100 "blunt" telescopes does give you a "sharp" one, on Earth and in orbit.

    It does when the position of each sensor relative to the position of the others matters. On earth that's trivial, but if you're 1.5 million kms out in space you could imagine this being significantly more difficult. Not to mention, each of these 100 units would require the same shielding from radiation as the giant one does for the same reasons. We chose L2 for a very good reason; where are these 100 going to go? What are the odds that each one will end up where it needs to be x100 attempts?
