This is a solved problem. When a proof is written, you should challenge the proof, not just reassert your intuition. You are ignoring islander A's view of B's view of C's view of ... Z's view of situation. Think about 3 islander's, where A thinks "if I have green eyes, then B and C are in a situation equivalent to me not being here, and B sees exactly 1 blue eyed person C, and B knows that 'C sees 0 or 1 blue eyed people, but then C learned that 0 is impossible'"
