It always makes me happy to see someone who is head deep into the star wars kool-aid punch bowl. None of your explanations matter because Star Wars is filmed like in-atmosphere dog fights, on purpose. Lucas wanted the esthetics of old aerial battles action flicks. Gravity, orbits, physics matters not at all. It became part of the visual language. None of the space battles in any Star Wars product make any logical sense in a world that has physics even slightly similar to our universe. But you know what? it doesn’t matter, you keep defending it. It is more entertaining that way.
