Look here, tough guy, even though Goku is one tough character, The Writer's powers are on whole 'nother level. He controls the very narrative that governs this match. His power encompasses reality and transcends all abilities. He's invincible, for crying out loud! Goku might be a God World destroyer but The Writer can manipulate reality at the highest level. That's like comparing apples to oranges, bud. The Writer's power is simply too much for Goku to handle. There's no way he can win against The Writer's god-like abilities.
