Projective geometry should allow for homomorphisms to the euclidean plane, see moebius transform. This creates the literal edge case, but then I don't need to take satelites for an analogy to see that. If I had reason to be afraid of falling of the edge, surely I could reason about circumnavigation as well. I really doubt that this is what flat earthers are worried about.
