You don't see how asking humans to multiply both sides of 2 * 2 = 4 by the same, very large, random-ish number, and expecting that they'll get different things

You don't see how asking humans to multiply both sides of 2 * 2 = 4 by the same, very large, random-ish number, and expecting that they'll get different things is relevant to this: > 2 * 2 = 4, but if you multiply both sides of that equation by a big number, that's no longer true. You know, the very same scenario I pulled from your comment?
