I don't know much about this topic, but I did RTFA, so permit me to ask a stupid question: 1. if this impossibility is related to noise overwhelming the image signal (thereby causing it to be an unresolved blur) 2. and if we assume that this 3.5-mile diameter is for a naked eye looking through a telescope (i.e. we're talking about a single exposure) 3. isn't there some statistical process that could enable a reduction of the diameter of the lens, which would reconstruct a less-noisy image based on multiple exposures?
